You can also avoid dealing with wet mishaps through it.
If you pick this Vortex scope, then I am sure that you will enjoy a clear view up to the lens’ edges. Another strength that it has is its highly protective lens designed to prevent scratches and scrapes. It is also one of those scopes that utilize the BDC reticles.

It can maximize the accuracy of almost all loads or calibers. This is made possible by its caliber-specific and 4x zoom technology as well as its completely multicoated optical system. (Learn more about the best scope for .308).
It takes pride in its large magnification range, which works together with the brand’s optical system, making it possible for it to deliver highly accurate shots on various conditions and situations. The 4x zoom technology I mentioned earlier is actually helpful in making the riflescope even more versatile. It is because it promotes a better range for low-to-high magnification.

You can even use this reticle in compensating for the bullet drop with ease in case your target is far.
The 4-12x magnification is also beneficial as it promotes highly accurate shots when used in medium and long ranges.
#8 Leupold VX-2 4-12x40mm Compact Riflescope

What Makes a Great AR-10 Scope?
The AR-10 is the predecessor of the widely popular AR-15 and although it is not quite as known as its successor, AR-10 rifles still remain as among the most sought after assault rifles by gun collectors. However, it is also a pretty practical rifle that you can use for both hog hunting and range shooting.
When it is chambered with 7.62/.308 rounds, combined with a good 3.6x telescopic sight, the AR-10 can hit targets as far out as 700m away. However, an AR-10 that has a 21-inch barrel combined with 9x+ scope can destroy targets that are more than 1,100 yards away, which is impressive considering that this is an assault rifle and does not belong under sniper rifles.
Aside from long-range shooting, you can also use the AR-10 in closed quarters and for medium range. Each of these uses requires the use of different scopes. For short-range shots, which means your targets are within 400 yards, you can make do with a smaller AR-10 scope with a 1x-4x zoom.
If you will be taking on medium-range targets, which means the targets are within 400 to 700 yard, then you will need a 4x-9x scope with an objective of 30-40mm. For a long range shot, which means targets that are beyond 700 yards, a scope with at least 9x magnification and a 40mm+ objective lens is what you need.
A larger objective lens allows more light to pass through the aperture, thus giving you a brighter and sharper image of your target. If you are looking for the best scope that you can use somewhat effectively for all ranges so you do not have to swap them out. You can use a scope that is in the 2x-12x range, although you will be making a lot of adjustments on the field.
Factors to Consider When Buying a Scope for AR-10
When buying a new scope for your new AR-10, you also need to take into consideration a couple of factors. There are so many different brands and models of rifle scopes for AR-10, which makes the process of choosing the right one for your particular needs quite tricky. You have to take your personal shooting style into consideration when buying a scope for your AR-10 rifles.
The first, and most important thing that you need to look for when shopping for a good AR-10 rifle scope is the magnification. As mentioned earlier, the magnification power of the scope will correspond to the range that you intend to shoot.
If you are looking for versatility, get a scope that has a wide magnification range, like say 3x-12x. However, you will have to compromise with the scope’s diameter, length, and weight. In addition, you will be adjusting the rifle scope quite often. It would be actually faster if you were to swap out scopes.
The next factor to consider is the diameter of the AR-10 scope. If you want clear sight pictures even when your target is more than a thousand yards away, you should get a scope that has a wide diameter. These scopes let more light in so you can get a clearer target sight.
This means that larger diameter scopes work best when you are shooting in low light or hazy conditions, like when you are out hunting. However, because the scope is much bigger, it will also be much heavier, so keep that in mind when shopping for the best scopes.
Type of optical glass used
Superior quality optical glass will make it easier for you to see the target much easier at any power magnification. The only way to get a feel of which scope uses the better glass is to do a side-by-side comparison. The differences may be minute but you will appreciate the added benefits.
Where you will be using the scope
Another important factor to consider is your intended use of the scope. For instance, if you will be using it as a hunting rifle then you need to avoid getting those complicated and very expensive scopes. Although those scopes tend to be more accurate, they are more prone to weather damage.
It is better for you to get a simpler and weatherproof scope, something that is easy to operate so you can adjust it on the fly. In addition, you should get a scope that does not add too much weight to your rifle. You need to travel light when hunting and every gram of gear counts.
The focal plane
Modern rifle scopes use a second focal plane for more accurate aiming. This means that the size of the scope’s reticle gets bigger or smaller depending on the magnification settings. This feature is quite helpful, especially for long-range shooting.
The reticle refers to the fine lines in the scope that help the shooter gauge distance and aim more accurately. There are different kinds of reticles available. These include mil-dot reticles, BDC (bullet drop compensation), and red dots, among many others. Each type of reticle provides different advantages depending on the shooter, so it is best for you to try out as many of the different types before settling on just one.
This might seem like a minor detail but you will find that it is quite important the more times you use your AR-10. Some AR-10 scopes come with adjustable eye reliefs, making it easier for you to make them comfortable to use.
There are also some scopes with a fixed eye relief that are kind of a hit-or-miss (pardon the pun). Sometimes, they fit you right away. However, there are also instances when they take a bit more time to conform to you.
Each type of scope has different elevation adjustments. For instance, long distance scopes have more elevation adjustment options to compensate for the many variables that come with shooting targets from a long distance away. In most cases, the larger the scope diameter, the more elevation adjustment options are available.
The objective lens allows light to get into the scope to give you a clearer picture of the target. The larger the objective lens, the more light can pass through. However, when the objective lens exceeds 50mm, the image tends to fade quite a bit.
If you will be using the scope mainly for hunting, you will need a scope with a large objective lens as the light conditions in most hunting areas are often less than ideal.
Frequently Asked Questions
Leupold VX-1 Versus VX-2 Versus VX-3I?
Leupold & Stevens is one of the US’ top rifle scope makers and has been in business for more than 50 years. The company’s top selling line of scopes are the VX series, which is their scopes that have variable magnification. The series is composed of the VX-1, VX-2 and the VX-3 model lines.
These are all top-notch Leupold AR-10 scopes and have gotten rave reviews from most of those who bought them. Now the question is what are the differences between the three scope lines? Which is the best of the bunch?
The Leupold VX-1 has lenses that have Multicoat 4 coating technology. This allows 92% light transmission. It has windage and elevation settings that are adjustable using a finger click setting with ¼ MOA increments and can go up to 52 MOA. The main tube is composed of two pieces. The VX-1 scope uses a classic-style focus eyepiece and a clear indicator for tactile power. The scope’s range has price ranges of $210-$300 depending on the model type.
The Leupold VX-2 uses coated optical lenses with index-matched Diamond Coat, and they also have blackened edges to help with focus. The VX-2 has a slightly higher light transmission than the VX-1 at 94%. The main tube is one inch in diameter and adjustments can be made in ¼ MOA increments up to 56 MOA.
VX-2 scopes come with externally threaded fast focus eye pieces and tactile power selectors. The VX-2 also comes with the 2nd generation Argon/Krypton filling, a fog proofing feature that prevents the scope from fogging up during rapid temperature changes. The VX-2 scopes also have rather steep price tags ranging from $300 to $600.
The Leupold VX-3 is the top tier choice of the three rifle scopes. The VX-3 has an Xtended Twilight System and Diamond Coat 2, which lets a massive 98% of light transmission. The Diamond Coat 2 is designed to transmit more light from the blue-violet color spectrum. This is the ideal scope to use if you are going on dawn or dusk hunts, the time when the game animals are most active. It is because those are the times when blue-violet light dominates thus giving you a clearer sight picture.
There are many models of the VX-3. Some models have adjustable objective lenses or side focus. Some models of this scope comes with a CDS feature (or an illuminated reticle with a motion sensor). The VX-3 scopes are the most expensive, ranging in price from $400 to $1,100.
Nikon P308 Versus M308
Aside from being one of the top camera brands in the world, Nikon, the company, also makes great rifle scopes, and their top sellers are the P-308 and the M-308. However, which of the two are actually better?
Although the M-308 has some distinct advantages, like:
- Parallax Settings
- Higher Magnification
- Large Range of FOV
- Large Range Of Eye Relief
The P-308 also offers almost same features as the M-308, but with the added distinction that it is almost half the price.
What mount to get for AR-10 scope?
There are basically two types of mounts that you can use on your AR-10. You go either with the one-piece mounts or the two-piece rings. For the AR-10, it is slightly better to choose a one-piece scope mount. Firstly it is because they are more rigid and stronger than ring mounts, and they also come already aligned. Although you can still choose the two-piece ring mounts if you want, they are lighter and are usually interchangeable between rifles.
How to mount scope on AR-10?
Mounting the scope is actually possible with these important steps:
- Secure the AR-10 on something that will not move, like your workbench vise.
- Level the rifle on the vise.
- Attach your mount of choice on the rifle. After attaching the mount on the rail, re-level everything. Place the level both parallel and perpendicular to the rifle, and place it on all the flat surfaces that you can find.
- Place your scope inside the rings. Be careful and ensure that there is enough clearance between the objective lens and the rail or barrel of the rifle and others like flip-up sights.
- Place the level on a flat portion on the scope, like the adjustment knob, and ensure that it is level both parallel and perpendicular to the rifle.
- Place the top of the mounting rings on the mounting bracket. Be careful not to move the scope. Apply a bit of Loctite and lightly tighten the screws on the mounts a bit at a time.
- Be careful not to strip the threads of the screws. Go around from corner to corner tightening each screw slightly until they are all tight enough.
- Re-check everything with your level then check if the crosshairs in the scope are aligned.
What is the best nightforce scope for AR-10?
If you will be getting a Nightforce scope for your AR-10, the one you should get is the Nightforce 2.5-10x. This is the best Nightforce scope for AR-10 because it is ideal for semi-close shooting, and can accurately fire a man-sized target for up to 800 yards. It also has a ZeroStop and a quick throw lever for easy use. The reticle for this scope might be a bit too busy for some but it does provide all of the information that you will need to hit your targets.
The AR-10 is a beast of a rifle and though it is not quite as popular as its predecessor, it is still a worthwhile gun that you can add to your collection, or even as your first semi-automatic rifle. To make full use of this magnificent firearm, you need to choose the right and the best scope for AR-10.
Sure, you can use the built-in sights for aiming. However, if you want accurate shots even from long ranges, you need a proper rifle scope. If you are going to use your rifle for boar hunting, deer hunting, or if you will just be shooting around in a gun range, a proper scope will ensure that you will always hit your intended target.
