How Much Range Does Rangefinder add?

Rangefinders are useful tools that are used in a wide variety of applications from construction to hunting and more. Laser rangefinders, also called laser telemeters, are the most popular, effective rangefinders out there. These devices use laser beams to determine the distance to an object.

The most popular laser rangefinders operate on the principle of time of flight by sending a laser pulse in a thin beam to the object and measuring the time it takes for the pulse to be reflected by the target and returned to the sender.

Laser rangefinders are extremely useful measurement tools that are indispensable in fields where precise and quick distance, slope, or angle measurements are required.

In this article, we’ll be taking a look at how much range can be added by laser rangefinders, in particular, as well as how they work. Read on to learn more about how much range does rangefinder add to your accuracy and shot.

How Laser Rangefinders Work

Laser rangefinders produce electromagnetic pulses in the form of laser beams from their optoelectronic systems. This beam is reflected off of the surface of the target and is returned to the rangefinder, which then processes the beam to calculate the distance.

The device measures the distance by analyzing the travel time in two planes, based on the phase delay of the produced and reflected EM wave. This is the method of measurement that is used in phase laser rangefinders.

Another laser-based method of measuring distance is to measure the pulse’s travel time directly from the rangefinder to the object and vice versa. Pulse laser rangefinders use this method, while some rangefinders use interferometric distance measurements.

This is most certainly the quickest and most precise method of measuring distance, but interferometric rangefinders are both costly and highly vulnerable to damage, making them unreliable in the field.

Laser rangefinders allow the user to take measurements both indoors and out, with 1mm/km accuracy. Professional construction-grade rangefinders are capable of measuring distance up to about 150 meters, while long-range devices can measure up to 1,500 meters

Why Use a Laser Rangefinder?

Compared to their ultrasonic and optical counterparts, laser rangefinders are the most technologically advanced and functional tools for measurements. Other than their extremely precise measurements, their main advantage is the fact that they only require one person to operate.

Optical rangefinders, which are used to take accurate distance measurements in large, open areas and at construction sites, require a minimum of two people to operate at once. This is why laser rangefinders are perfect for hunters and shooters.

They are also less prone to measurement errors caused by improper positioning and other human errors. Additionally, laser rangefinders come with auto-calibration features and electronic alignment aids, and they allow users to take measurements based on the ‘painter’ function, otherwise known as the Pythagorean equation.

You can use them to take delay measurements and continuous measurements, measure the difference or sum of a surface, and calculate volume. Clear screens and advanced processes that are installed in laser rangefinders significantly improve their usefulness and functionality, as well as their accessibility.

Maximum Distance

Laser rangefinders have seen some drastic improvements since they were first introduced to the hunting scene around 25 years ago. These days, most models can provide accurate readings within one or two yards up to a mile away, sometimes even farther.

Even at the most budget-friendly end of the spectrum, there are few rangefinders on the market that aren’t able to range accurately out to about 400 yards, which is farther than most hunters will ever shoot at big game animals. If you primarily enjoy bow hunting, you likely won’t need a rangefinder that can give you the distance of an object more than a mile away.

Aiming Point

The aiming point of a rangefinder, also known as the reticle, is the object at the middle of the viewfinder that is placed on the object that you are trying to determine the range of. With most rangefinders, when you focus the aiming point on your target object, you simply press a button to turn the laser on.

The laser beam will then travel to the object, bounce off of it, and return to the rangefinder, which will then halve the distance and display the object’s range on the screen. Some aiming points are easier to hold steady on the target object than others.

Because the ideal aiming point is largely a matter of preference, you should try several different rangefinders before spending any money.

Magnification

Magnification is another important component in any rangefinder. It is an essential factor, as many hunters often range animals that are very far away, making seeing them nearly impossible. Plus, ranging them is even harder without magnification.

On a rangefinder with 6x magnification, the target object that you wish to range will appear six times bigger than it does in reality, allowing you to place the aiming point on it with ease. Note that several companies produce binoculars that come with integrated rangefinders. This can be useful since their magnification is generally 10x or more.

Size

When rangefinders were first created, they were rather bulky, cumbersome, and a general burden to carry around. These days, most laser rangefinders are small, and many models could even be called tiny.

Regardless of the rangefinder you choose, ensure that it fits your hand comfortably and that your finger can rest directly next to the button that turns the laser on. If you have larger hands, then the smallest rangefinders on the market may not be suitable for you.

If you do opt for a tiny rangefinder, you should be sure to pick a safe place in whatever bag or backpack that you use to carry your equipment and always keep it in that exact place. If you don’t, you run the risk of losing it and searching for it when you should be focusing on other things out in the field.

And there you have it – everything you need to consider when it comes to rangefinders!

How to Use a Hunting Rangefinder

Accurate shooting starts with your understanding of the distance between the target and your position. Knowing this measurement allows you to make accurate shots that are more ethical and humane. Plus, it means you can have a cleaner harvest. A rangefinder is an ideal accessory to help you confirm your shooting range with a simple look through its lens.

Ironically, a rangefinder is typically the last item a hunter will purchase after their spotting scope, binoculars, and scope. And although you may think it is a luxury item, this couldn’t be further from the truth. No matter what level of experience you have, we can all make bad distance judgments. Here we will look at how rangefinders work and how to use a hunting rangefinder to make sure you never go home empty-handed. So without further ado, let’s get right into it.

Rangefinders – How They Work

Before we look at how to use your rangefinder, you need to understand how they work. The most common type of rangefinder used for hunting is a laser rangefinder due to its accuracy. It works by hitting your target with a laser then measuring how long it takes for the laser to return.

The laser’s set speed in relation to how long it takes to return determines your target’s distance. Laser rangefinders are typically accurate to within 1 yard or less. Once measured, the range will be displayed in either yards or meters on the LCD, usually in 1 second or less.

How Does a Rangefinder Help?

Depending on your model, a hunting rangefinder is accurate within 600 to 1,200 yards, sometimes even more in high-end models. For reflective or hard objects, like rock, you measure them at even greater distances than what you could measure softer targets such as game animals. Semi-hard targets like trees are somewhere in between.

Most rangefinders will have a spec list that indicates the maximum range you can measure for various targets. Every manufacturer has a name for it, but most rangefinders will have a feature that offers true horizontal distance, which compensates for variations in angle and terrain.

Rangefinders are very helpful, especially for long downhill or uphill shots or shots at an extreme incline or decline. This is because the distance to the target is different from what it would be at ground level. Using the rangefinder will allow you to include ballistics and gravity compensation.

How to Use a Hunting Rangefinder

Now that you know how your rangefinder works, let’s take a look at how you go about using a hunting rangefinder.

Before Staring, Check the Rifle Scope

One of the most vital uses for your hunting rangefinder happens before you start your hunt. When unpacking your gear, you should do a test shot to ensure that you are sighted in properly. You can do this by ranging a target in the distance and check if the bullet hits the mark with where your scope says it should. Things as small as jostling in transit or using a different bullet brand can throw it off by up to an inch. This could result in a messy kill or missing the target entirely.

Don’t Wait Until the Last Minute to Range the Target

The time for figuring out distances is before the target shows up. The last thing you want is to have a big buck walk into your line of sight, and only then do you reach for the rangefinder. From your position, scan the surrounding area to get a sense of your potential shooting lanes. Make a note of the distances so you can save precious time when your prey appears.

If possible, it is even better to mark various landmark trees earlier in the day. From the position you will be during the hunt, use your rangefinder to measure the distances to trees and spray paint them with dots – 2 for 20 yards, 3 for 30 yards, etc. By doing so, you don’t have to remember the yardages mentally. This preparation before can pay off big time later.

If You Must Wait Until the Last Minute to Range the Target

As mentioned above, it is best to range your target beforehand. Still, sometimes the prey moves differently to how you anticipated… or you just forgot. When you have a target on the move, rangefinding works a bit differently. Your instincts may tell you to place the reticle on the target, but by the time you’ve packed away the rangefinder and lined up the shot, the target will be at a different distance.

Rather, take a few seconds to work out where the animal is moving to. Look at the predicted location and plan the shot’s distance based on that estimation. Hopefully, this will give you enough time to put your rangefinder away and get your shot ready and steady before the prey gets to the kill zone.

Using the Holdover Calculator

If you are hunting from a treestand, you will be at a steep angle to your prey, which can easily lead to misjudgments in distance. This is because your brain can better sense distance over a flat field than at an angle.

This is where a holdover calculator comes in. Most higher-end hunting rangefinders have this calculator, which ranges the path your bullet needs to take to hit a target taking into account the added elevation required to counteract gravity.

For the holdover calculator to work effectively, you must program your shot velocity based on your ammo. Once calibrated, you can use the calculator to give you the information you need to shoot your target accurately.

Final Words

If you are new to hunting or are looking to increase your accuracy game for better precision, a hunting rangefinder is a must-have item. As you can see from the above discussion, they have numerous benefits, including better shots, cleaner kills, and more humane hunting overall. By following the above guide on how to use your hunting rangefinder, you will experience better hunting than ever before.

How Does a Red Dot Sight Work - gunsafetips.com

How Does a Red Dot Sight Work?

Red dot sights are an excellently innovative optic that is designed for use in close to moderate distances. Its value comes from its simplicity and use of clever technology to create an accurate optic that anyone can quickly acclimate to without needing to spend very much time on shooting practice.

There’s more to it than that, though. The red dot sight has many benefits that make it as popular as it is. When you get an optic as versatile and straightforward as this, you can’t help but wonder what makes it tick.

So how does a red dot sight work? Below, we’ll be looking at the answer to this and why they are so popular and easy to use.

Origins of the Red Dot Sight

Newcomers are always surprised to find out that there is very little new technology in modern firearms. Red dot sights are by no means a new or recent invention, with their roots tracing back to over a hundred years ago. However, the red dot sight as we know it today has only been around since the mid-1970s.

Red dot sights are reflex sights, or more accurately, a more modern rendition of the reflex sight. Reflex sights have been used historically on rifles and snipers to provide an optic that is easy to use and that is reliable without the necessary hassle of operating and maintaining a scope.

The idea behind the reflex sight was to take in light from a small window on the top that would shine on a piece of reflective glass that lay at an angle inside the optic. This would essentially allow an image to be reflected inside the sight to create an image projected to what was effectively infinity. This would enable quick, accurate shots that were easier to pull off on smaller firearms, hence the term “reflex” sight.

The result used light that was reflected through a concave piece of glass to create small and simple shapes that would be used as reticles for easier aiming. The cost of this was a sacrifice in magnification, so reflex sights would not be suitable for any kind of long-distance shooting.

That was back then, though, and the reflex sight has seen much overhauling and experimenting. We now see many different types of reflex sights that still use the same concept of reflected light through a curved lens to create a projected image. The red dot sight is one such reflex sight, and as we have mentioned before, it is relatively recent in its innovation compared to most items in the firearm industry.

Now that we have an idea of the history of the red dot and the reflex sight’s core design, we can look at how that idea has been updated using modern technology, as well as exactly how the contemporary reflex sight works.

The Red Dot Sight – A Modern Reflex Sight

The red dot sight we see nowadays isn’t that different from the old design, but it does incorporate new technologies that didn’t exist back then. Over the years, many other optics have come about from that initial design, and anyone who plays modern first-person shooter games probably has an idea of some of them.

The red dot sight, in particular, is uniquely simple in its design. Using two curved lenses in the optic, one in front and the other in the back, you can create a tube of sorts for light to travel through. Some of the smaller sights have these two lenses close together, such as on pistols, but the distance doesn’t necessarily matter.

From this point, there are two different avenues that manufacturers can take. They can develop a passive system that is powered solely by light or an active system with an actual power source built into it.

To put it simply, passive systems have images of the reticle etched into the two reflective lenses’ glass. These images are usually made from a different reflective material, copper being a common option, and are typically placed either at the focal point of the front lens or at an angle inside the scope housing.

With angled placements, the angled lens will project and magnify the image onto the focal point of the front lens. The glass lenses are also often treated to only let red light through, thus creating the red dot effect, but there are red dot sights with different colors, such as green or cyan.

Active systems are passive systems that don’t need to rely on external light sources, as there is a lighting system built into them so that you’ll always have light handy. LEDs are used because they shine brightly so that you can easily distinguish the sight from the target on the other end of the reticle.

Thus, when light enters the optic or scope, the image etched into the lens will illuminate and magnify thanks to the curved lenses. This makes the tiny reticle appear much larger thanks to a simple magician’s trick from years ago.

In short, the light goes in, is reflected around inside the optic, and the reticle lights up for aiming.

Different Types of Red Dot Sights

A few different variants of the red dot sight use the same technology to varying degrees for different effects.

Standard rifle optics are the most common variety of red dot sight and can be considered a benchmark or baseline. They are often a 2 or 3 MOA red dot that is for more moderate to close ranges. The larger the dot is, the easier it is to spot on the reticle and the faster you can train it on the target.

Miniature red dots are tiny and are for smaller firearms, such as pistols. These red dots are mostly used for pistols and as backup rifle sights, and they are characterized by their dot being significantly smaller than others. Because of their smaller reticle, it’s far easier to spot the target, but it can be more challenging to spot the dot on your reticle, so you may have some difficulty training your dog on the target initially.

Conclusion

Red dot sights are continually being upgraded and updated, but they are by no means a new invention. Their roots go even further back than the 1970s when they were first used. They are a wonderfully simple design that is an excellent choice for anyone looking for an easy-to-use optic in close to moderate ranges.

Red Dot vs Holographic Sight - gunsafetips.com

Red Dot vs Holographic Sight: Which One to Choose?

Red dot and holographic sights are two different forms of firearm optics designed to assist in long-distance targeting and firing, amongst other shooting activities.

Red dot sights have existed and have been utilized recreationally for years, having first been designed in 1975; holographic sights, on the other hand, were only invented at the turn of the 21st century.

Red dot sights remain far more ubiquitous amongst recreational shooters. While holographic sights are being used recreationally to some extent, they are more commonly used in the military, having replaced red dot sights therein.

But which is better when affordability and value for money, accuracy, target acquisition, and durability is taken into consideration? Read on to find out which one you should choose!

Red Dot vs Holographic Sight: A Comparison

Affordability and Value for Money

For budding shooters looking for a firearm optic on a budget, red dot sights are the only option. Given how long red dots have existed and how less complex they are to make compared to holographic versions, you can pick up a basic red dot sight for under $50. Some of which, like the Tasco Propoint, perform exceptionally well for their low price and are a perfect option for beginners.

However, if you are looking for more out of your red dot optic – i.e., increased accuracy and durability – you’re looking at prices around the $200 mark. It is worth noting that mid-range, high performing red dots are available for under $100.

When it comes to holographic optics, however, things are slightly more on the pricier side. Given that only two companies – EOTech and Vortex – currently produce holographic sights, it’s impossible to find a cheap equivalent to the military standard.

The most basic holographic sights have a starting price of roughly $400 – which is about the same price as a high-end red dot sight. However, bear in mind that this is only the starting price and that a more advanced holographic sight will take you well into the thousands of dollars range.

So, with that considered, it’s fair to say that red dot sights are the best bang for your buck.

Focus and Accuracy

In lots of ways, similarities can be drawn between both red dot and holographic sights in terms of ensuring target accuracy. For example, both red dot and holographic sights boast brightness settings and feature night vision capabilities.

However, one way in which holographic sights are better than red dot sights is regarding magnification. When magnifying a red dot sight, the red dot will appear bigger without upscaling the target it is aiming for. This is a major disadvantage as it renders the target’s position within the now magnified red dot reticle impossible to determine.

On the other hand, when using magnification on a holographic sight, both the sight and the target maintain their original proportions, which ensures that accuracy is maintained.

Additionally, if the user suffers from short-sightedness or astigmatism, red dot sights will become blurry when focused upon. On the other hand, holographic sights place the reticle upon the target, allowing for the target to remain in focus at all times, which ensures utmost accuracy in shooting for the visually impaired.

When it comes to accuracy, it’s fair to say that holographic sights are by far the better option.

Target Acquisition

One major difference between holographic and red dot sights is, of course, how the inner technologies of each work. For red dot sight, the distance between lens and focus is the sight itself, as the red dot is focused to your eye.

This renders target acquisition much slower when using red dot sights, as your eye cannot focus on both the target and the red dot simultaneously.

On the other hand, the far more technologically advanced holographic sight uses its complex inner mirror system to superimpose the reticle on your target in front of the sight. This is an advantage for holographic sights, as you, technically, can focus on both the reticle and your target simultaneously.

Target acquisition is, therefore, much cleaner and quicker when using a holographic sight.

Durability

For red dot sights, durability is only really determined by how much you’re willing to spend. The cheap, below-$50 red dot sights available will be great for airsoft and other basic shooting activities – which is what they are designed for. However, these low-range models will break under continued recoil and general usage.

The mid-range and more expensive red dot sights, made from aluminum, will hold up for much longer under pressure.

Given the minimum price of a holographic sight, on the other hand, you’d expect a piece of kit with the utmost durability – and they certainly deliver. Designed for combat, holographic sights, at a bare minimum, will weather fire, water, and bombs – with ease!

Holographic sights can even continue to be operational with the front window smashed, damaged, or covered in mud. With that, it’s fair to say that holographic sights are far more practical on the durability front!

Battery Life

It is battery life where the red dots truly excel in terms of durability. The cheapest models promise a battery life of two to three years, which is still exceptionally good. But some of the more expensive red dot sights can function on the same battery for up to 50,000 hours of continuous usage.

Red dot sights excel completely over the battery life of holographic sights, which averages at about 500 hours, with a maximum of 1,000 hours.

With that in mind, as long as they remain undamaged, red dot sights are more durable in terms of battery life.

Conclusion

Overall, both holographic and red dot sights have their pros and cons, rendering it difficult to determine which form of firearm optic truly has the advantage over the other.

In terms of recreational use, the red dot is really all needed, given its affordability, brightness settings, night vision, and extensive battery life. The holograph, too, has its advantages, including its accuracy, durability, and faster target acquisition.

How to Zero a Red Dot Sight - gunsafetips.com

How to Zero a Red Dot Sight

If you want to improve your target acquisition, the quickest way to do that is to install a red dot sight on your rifle. However, it does not help you a lot if the red dot sight is not calibrated correctly or zeroed on your weapon.

We will take a look at the simplest ways to zero your red dot so you can become more accurate and have more fun. That is mostly why you want to learn to fire your weapon, to become more accurate with your shooting.

So, if you want to find out how to improve your shooting, you need to learn how to zero a red dot sight. Keep reading to find out how to do that.

Why a Red Dot Sight?

The main reason you would want to have a red dot sight on your rifle is to improve your accuracy. This is especially important for beginners who are new to the sport of target shooting and target practice.

Red dot sights are also very easy to install on your firearm, and they are relatively easy to use for fast target requiring. You just need to put the red dot on the target and pull the trigger; that is how simple it is.

How to Zero a Red Dot Sight With a Firearm

There are a number of steps you need to follow when you want to zero the red dot sight on your firearm. First, you need to calibrate the red dot sight, so the red dot is squarely center and on top of the front sight post.

We will take a very simple approach not to bore you with technical terms such as MOA and mechanical offset. This is a straightforward method to get you ready to shoot your firearm more accurately, so follow these simple steps.

  • Set up your target at 25 meters from your shooting position.
  • Place your firearm at rest and aim on the target; make sure the barrel is not rested on anything.
  • If the red dot is to the left of your front sight post, turn the dial to the left to get it centered on the front side post.
  • This will move the dot to the right and more to the center.
  • When you find that the red dot is situated to the right of the front sight post, turn the dial to the right. This will bring the red dot to the left and back to be center on top of the post.
  • As you can see, you need to turn the dial in the opposite direction you want the red dot to move.
  • If the red dot is too low or too high, follow the same procedure with the Y-axis dial; the same principle counts here.
  • Now you can center the red dot on the bulls-eye of the target.
  • Take a shot and take a look at the point of impact.
  • The safest way is to use a target with a small square grid to make it easier to know how many clicks you need to turn.
  • If you shot to the right of the target, you need to use the same principle and turn the dial to the right. An impact to the left of the target needs to be adjusted in the opposite direction.
  • The same will happen if the impact on the target is either too low or too high; the opposite direction adjustment also works here.

The Technical Way

Take a target and draw a 1-inch square grid on the entire surface of the target. So if you have a 25 inches x 25 inches target, you will have 25 x 25 1-inch squares all over the target.

Now you need to take a look at the red dot; you will see that you have windage and elevation adjustment knobs. The one saying UP is the elevation adjustment, and the one marked with an R is the windage adjustment.

If your red dot sight says it is a 1 MOA sight, you know that means 1 inch at 100 yards. So if your target is at 100 yards, every square on the target represents one click on the elevation and windage adjustment knob.

Place the target at 100 yards with your bulls-eye in the center of the target and aim for the bulls-eye.

If the point of impact after you took a shot is, say, 2 blocks to the left and 3 blocks lower than the bulls-eye, you will have to adjust the elevation with 3 clicks on the knob down, and on the windage, you adjust 2 clicks to the right. This will move the zero on your red dot sight up and to the right to be closer to the center.

Keep in mind that if you put the target at 50 yards, that means you will now have a half-inch MOA. This means you need to double the number of clicks to the left or right and up and down.

If you place the target at 25 yards, you will have to multiply the number of clicks by 4 because it is now a quarter-inch MOA. That is why it is important that you need to know your sight and what the information on it means.

MOA is an acronym for Minute Of Impact, which is basically a measuring unit for target shooting.

Zero With Other Weapons

If you are not a firearm user but rather go for crossbows, the method to zero the red dot sight will be the same. All the adjustments will be made on the sight to get it calibrated and to zero the sight for accurate shooting.

Final Thoughts

As you can see, you do not really need to be an expert to zero a red dot sight, but it will be useful to know one. It is always best to ask for help than to struggle on your own to improve your shooting.

See the following Youtube video on how to zero the red dot using this MOA principle without it being too technical.

Where to Mount Red Dot Sight on AR-15 - gunsafetips.com

Where to Mount Red Dot Sight on AR-15?

Gun and shooting enthusiasts love the classic, reliable red dot sight. Whether you’re into guns and gun mods or not, you’ll likely know about this optic from games or movies. It’s popular, and if you’re an enthusiast, you’ll probably want to have at least one in your collection.

The main reason they’re so popular is that they are designed to simplify most aspects of shooting your AR-15. Offering quicker and easier transitions from target to target, excellent peripheral sight, and simple installation, the red dot sight has quickly become a staple.

However, these are only aspects you can begin to enjoy once you’ve got a bit of experience under your belt, and experience comes with use. Unfortunately, that means you’ll have to fiddle around and figure out how best to mount the sight first. Luckily for you, we’re here to help.

Read below for advice on how and where to mount your red dot sight on your AR-15!

How Far Back Should You Go?

Red dot sights are among the most versatile sights and can be fitted to almost every modern gun design. Moreso, they have the excellent characteristic of having unlimited eye relief, so you can experiment with where exactly you mount your sight. It is designed so that the little red dot reticle and your target will remain the same size no matter where you put it on the rail.

This means that the mounting process is very simple. All you need to do is mount your sight, zero it for accuracy, and then get to shooting.

The most common platform for red dot sights is on long guns. These include rifles, shotguns, and pistols that are more rifle-like in design. These also include the AR-15, which we are looking at today.

You’ll most likely have a Picatinny or similar rail, as these are the most common types of rails across the board for long guns like the AR-15. Similar to the red dot sight, the Picatinny is one of the most versatile and universal rails, and it can be installed on any gun that can support it.

Do you remember that unlimited sight relief we mentioned earlier? This means that you can install your red dot sight wherever you want on your rail as long as it’s forward of your cheek weld. For those who do not know, this is the action of placing your cheek against the buttstock’s comb to help maintain accuracy.

Now that we have a point of measure of how far back we should go – not past your cheek weld – let’s start mapping out some points along the rail that you can experiment with.

Places To Consider

Most modern rifles support rails long enough to extend from the receiver to the end of the barrel or as close as possible. This means we’ve got quite the space to work with when looking for points to install our red dot sight.

For a beginner, many experienced shooters recommend mounting the red dot sight above the receiver. This is because modern rails can have some flex to them, causing them to vibrate quite a bit while shooting. With your sight closer to the receiver, you can help minimize these vibrations so that your zero is more accurate.

Generally, going forward beyond the receiver is a bad idea. The further away from the receiver you go and the closer you get to the barrel, the more flex you’ll experience on the rail and the less accurate you will be. On other take-down guns, it may make sense to mount the sight closer to the barrel for more precise shots, but it is ill-advised for our purposes.

However, it isn’t always possible to mount the sight above the receiver, such as when using additional attachments or mods that would come before the red dot sight. In this case, you should still be mounted close enough to the receiver to help maintain accuracy but not close enough to create any discomfort.

The sweet spot that many seem to enjoy is right above the ejection port for the reasons we’ve covered above. It will allow you to maintain accuracy and balance when shooting without necessarily sacrificing space for attachments such as a magnifier, or zoom, as some call it.

AR-15 with Red Dot Sight

Zeroing

We’ve mentioned it a few times before, so let’s briefly talk about zeroing. This is the next step after you’ve mounted your sight to your rifle. Essentially, it is making sure that your sight is accurate for the type of gun you’re going to be shooting.

You wouldn’t zero your AR-15 like you would a shotgun or pistol. For a red dot sight on this gun and similar types, you’ll want to zero it at 50 yards, which will virtually take you out from 50 to 200 yards.

Most red dots will have two dials that control the elevation and windage. Some might have these two configurable features in one dial, so make sure you consult your manual for your specific design. These dials will work with MOA measurements most of the time, with each click representing one adjustment.

MOA represents one inch at 100 yards, and most dials will adjust in quarter-MOA increments, so one click at 100 yards is one-quarter of a movement on the dial.

Steps to Mount Your Sight

To close off this article, we’ll give you some tips and the general process of mounting your sight that should be followed. You can actually mount your sight in a few simple steps.

Firstly, you’ll want to use a threadlocker to ensure the screws of your sight and the mount do not come loose with the gun’s vibrations. Of course, we want to maintain accuracy, so ensuring that your screws are firmly in place even after several shots will ensure that you remain zeroed.

Secondly, when tightening your sight in place, push ever so slightly forward. This will ensure that your gun’s backward recoil won’t affect your optics as much. You want to keep your optics more stationary when shooting so that you stay accurate.

Final Thoughts

Hopefully, you are now more knowledgeable about how and where to mount your red dot sight, and you can now enjoy being more accurate at the shooting range!

Why Do We Need To Use Security Systems In Our Homes?

In the face of growing frequency of and better awareness of worldwide threats, effort and spending on security continues to increase both from homeowners and business owners.

Security systems have become more sophisticated than ever, with more features and options now available to the average homeowner. While historically a few key security systems were available, such as ADT and Brinks, new technology and modular systems are now available to satisfy a homeowner’s every whim. Companies like Nest and SimpliSafe offer homeowners the ability to monitor every doorbell ringer and alert the owner’s smartphone during any sensor activation.

Of particular interest is the growth of the highest end of security options, including features once thought to only exist in movies!

A plethora of high profile individuals have been highlighted in the news showing their major investments securing their homes to be almost a fortress. In Vanity Fair’s February 2018 article “Does Peter Thiel Know Something We Don’t” the author talks about Thiel’s recent investment in a sophisticated security defense, most impressively his large and secure safe room. His panic room is designed to likely include biometric access with barricaded walls and blast doors, communication features and many other non-disclosed features.

With Thiel owning homes in many locations around the globe – from Miami to San Francisco – this home with its special security feature is in his New Zealand residence. According to many, such as LinkedIn’s co-founder Reid Hoffman, a New Zealand home purchase by a silicon valley elite is an obvious signal that the purchaser is intending the residence for secure use at an end of the world, apocalypse-type scenario. Apparently, many consider New Zealand to be the rare first world country that also offers remote locations to live in.

Many different well-known threats pervading the media increase our collective awareness of the need for safety. Terrorism seems to have had an uptick, from France to the United States. A few comments on any of many terrorist-related events in recent years creates almost immediate memory of the event for most people.

In 2004, a series of coordinated, simultaneous bombs erupted in Madrid’s train systems days before a major Spanish election, inuring over 2,000 commuters and killing 192 people. In 2011 a major bombing in around Oslo, Norway killed 77 young people, the largest attack in the country since World War 2. London bombings in 2005 paralyzed the cities transportation for months. In 2016, the harrowing Nice, France attack is still fresh in many people’s mind, when a 38,000lb transportation truck barreled down a crowded walkway, killing 87 unsuspecting people. Many more large and small-scale attacks have occurred in just the last 5-10 years.

Social unrest has also recently come to a head within the US, not seen since social unrest during the 70s and other times of major change. In Missouri, a hotly debated case involving police and a fatally shot civilian plunged the city of St. Louis into chaos. Individual business and homes were targeted as a minority – but still very large – group of protestors turned violent.

To preserve the peace of mind, many luxury homeowners have sought to establish their homes with much more sophisticated security measures that would have previously been considered. Those in the higher echelon use an array of physical and digital security to deter threats.

The exteriors of these homes often include the most impressive physical security. For the first line of defense, gates are installed around a property, as a major deterrent. Wealthier individuals may employ a part- or full-time guard to cover the main entrance. Flimsy wood doors are replaced with strong iron doors since most break-ins occur there. However, windows are also a common target. These can be significantly reinforced whether through weaker tempered glass or all the way to ballistic glass for the home’s windows. Access to the home may be controlled via biometric access, such as a fingerprint reader.

Inside the home are other features, including defensive measures, like panic rooms. Offensive measures may be present too. Some homes are installed with smoke valves: if an intruder gains entry into the home and a sensor is activated, smoke may fill a critical room to disorient the intruder while a family can gain precious seconds to reach a safe location. Commonly in America, firearms may be covertly stored in one or multiple areas within the home for use in an attack situation.

As greater awareness of national and worldwide crises continue, the trend toward more sophisticated security both for the highest echelon of society and the average homeowner will likely continue as well.
