Primary Arms 4-14x44mm FFP RiflescopeBest Mid-range Scope

Features
  • Magnification: 4 – 14 x
  • Objective lens diameter: 44 mm
  • Eye relief: 3.14” – 3.22”
  • Field of view: 7.85 – 27.2 ft at 100 yds
  • Reticle: ACSS HUD/DMR
  • Weatherproof: yes
  • Length: 13”
  • Weight: 24 oz.

Other features: FFP, finger adjustable turrets, shockproof, 3-year warranty

The Primary Arms line of scopes are made in China and are popularly known for being a budget brand. The scopes are a great buy for the money. This particular model packs a punch with a myriad of powerful features and beastly performance but it is specifically made for the 308. You wouldn’t make the most of it if you have an AR-10 chambered in another caliber.

The scope has a tough build fit for the tough conditions in the outdoors. It has a weatherproof and shockproof design, therefore you can trust it to last you a while. Its turrets are also ergonomically designed for superior comfort and ease of use. You can adjust them with your fingers even when wearing gloves to calculate distance and wind bullet impact.

The scope is known to offer the best first focal plane experience. This means that as magnification power changes, the MIL and MOA adjustments stay the same allowing you to quickly find and hit your target accurately despite the distance or its size.

In addition, the scope’s glass is pretty decent for its price. It offers incredible clarity and focus ability when sighting for long-range or target shooting.

The only downside to this scope is that although its reticles are specifically made for 308, its Bullet Drop Compensator (BDC) functionality can only work with bullets of certain weights and speeds. If you shoot a configuration that is not aligned with the preconfigured BDC functionality then it won’t work right for you.

On the flip side, you get a 3-year warranty backup and that is why this scope is one of the best scopes for AR-10 .308. Plus, you don’t have to make a hole in your pockets to get it.

Why are we impressed?

  • Durable build
  • High-quality glass
  • Best for AR-10 chambered in .308
  • First focal plane
  • Pocket-friendly price
  • 3-year warranty

What negatives must you be aware of?

It offers pretty decent features and exceptional mechanical performance for its attractive price point. Btw! You don’t need an expensive scope to kill animals anywhere in the world. You may want one but you will never need to decimate your bank balance for a scope to sit on top of your rifle.

As you’d expect of all Leupold’s products, this scope is durably built with an elegant matte black finishing. You will hardly notice its impressive 13ounces weight on top of your rifle. This comes with a cost though, if you are used to the parallax feature or an illuminated reticle system on a scope, you might want to look elsewhere. Their absence makes the scope lightweight.

You will not have any trouble zeroing the VX-Freedom owing to its turrets that are clearly numbered and include finger-click adjustments underneath for elevation and windage.

Another impressive thing about this scope is its generous eye relief that ranges between 33/4 inches when magnifications are higher and 5-inches on the lowest magnifications.

Essentially, this scope features Leupold’s famous propriety coatings; the Twilight Light Management system. Together with other elements of the scope, the coatings enhance light transmission as well as improve the vibrance of colors and contrast of highlights in low-light conditions. They also reduce glare effects, thus the best for hunting at dawn when the sun comes out and at dusk when there is little to no light.

You will also make the most of the 7 brightness settings.

In sum, this is one of the best scopes for AR hunting that money can buy. Leupold doesn’t skimp to cut the price, you get as many features as you would need for your basic hunting activities without breaking the bank.

Not to mention, the scope is incredibly lightweight. It weighs a mere 14.6 ounces which is ideal for any hunter always on the move stalking their prey.

The scope has superb glass quality that facilitates optimum light transmission for the brightest and clearest images even in low-light conditions at dusk or dawn. The flip side of this scope’s glass quality is that it has a bit of distortion as the magnification power increases. It’s not entirely useless but still noticeable.

If you are into long-distance shooting, this should be your go-to scope. It features the Dead hold BDC reticle which makes long-range shooting easier. All you have to do is zero at 100 yards then guide your shot with the hash marks.

The scope has 3.1 inches of eye relief which isn’t the most generous but still enough to get the job done. In fact, you will only feel the eye relief inadequacy at the highest magnification setting. This is because the eye-box gets a bit tight at this magnification level but a good cheek weld and perfect mounting hardware can solve this problem.

Another plus for this scope is its exceptional turrets. They are finger-adjustable and they zero in fast and hold zero well. They also produce positive click sounds.

Moreover, its 4-12x magnification is ideal for medium to long-distance shooting. It is also parallax-free from 100yards onwards thus a prime option for hunting.

Features

  • Objective lens diameter: 50 mm
  • Eye relief: 3.3”
  • Field of view: 16.7 – 4.5 ft at 100 yds

  • Weatherproof: yes
  • Length: 14.1”
  • Weight: 30.3 oz.

Other features: FFP, MOA, LED illumination, fully multi-coated optics, ring mount

This is by far the best scope to get if you are just getting started on long-range shooting. This Athlon Optics scope performs like a thousand bucks yet it’s nearly quarter the price and that’s a fact. Not a marketing hype! Unlike many cheap scopes, it doesn’t skimp to cut the cost. It simply just makes long-range shooting possible for novices.

With such a price point, you’d expect a mediocre build that would falter after a few uses. Not with this scope. It is ultra-durable, as it is crafted from aircraft-grade aluminum, nitrogen purged to prevent internal fogging as well as O-ring sealed to make it completely water-tight.

Additionally, its lenses are coated with XPL to protect it from oil, grease, sand, and dirt. You can use it almost anywhere in the world without worrying about it getting damaged.

You will love how spongy and easy the elevation and windage knobs are. They move easily without any resistance which is good and bad. Bad because it could lead to over adjusting and mess up your settings. Though you can solve this by wiping out the factory grease on the turrets and re-greasing it.

The scope features a super clear and crisp glass construction. Though it can get blurry at higher magnifications. On the bright side, the scope can perform in bright light, low-light, or no-light conditions thanks to its illuminated reticle. It even has 11 brightness settings knob that you easily adjust to suit your lighting condition and preferences.

What’s more, the scope is a first focal plane, a feature mostly found in high-end scopes. Therefore, it is an ideal choice for long-distance shooting as its holdovers don’t change regardless of the magnification setting you are on. You wouldn’t have to calculate windage or holdover, or even make any adjustments. All you have to do is zoom.

Now the biggest downside to this scope is its limited eye relief. If you have a heavy recoiling caliber, you might find it a bit too tight, but with a good cheek weld, it can do the job.

The scope’s magnification is wonderfully versatile and clear but not the best for extreme long-range shooting as it tends to get blurry at higher settings. Its parallax adjustment knob is also a charm as it turns smoothly and accurately.

With an eternal warranty, this is the best scope you can get for long-range shooting at its price point. It offers all the fancy long-range features only found in top dollar scopes at 1/3 the cost.

What are our favorite features?

  • Durable construction
  • Great quality glass
  • First focal plane
  • It has long-range capabilities
  • Illuminated reticle
  • Dead-on tracking
  • Offers excellent value for money
  • Lifetime warranty

Things to Consider

For you to buy the best scope for your AR-10 rifle, you must consider a couple of factors including your personal shooting style, the multiple brands and models available on the market, and a few must-have features. This section contains all the information you would need to gain buyers’ confidence when you go shopping for a scope. You will get to know the best scope for AR-10 and some of the features to consider when choosing one.

What is the best scope for AR-10?

10 Best Scopes for AR 10 - Reduce the Risk of Missing Your Target to the Minimum!

An AR-10 rifle can be used for various purposes like hunting, marksmanship and more. It offers a reliable and painless shooting experience. You can choose to use yours for either long, short or medium-range shooting. For each of these, you would need different types of copes.

For the short-range shooting of targets within 400 yards, you can use a small scope with 1-4x zoom. For medium-range shooting, with targets within 400 to 700 yards, you can make do with 4-9x zoom and a 30 to 40mm objective lens scope. For a long-range shot, which means targets beyond 700 yards, you will need a scope with 9x magnification and an objective lens of 40mm and above.

You can also get a versatile scope that you can use for all the ranges. Its magnification range would be 2x-12x with a larger objective lens but you will have to do a lot of adjustments on the field.

Features to consider when choosing the best scope for AR 10

Here are some of the most crucial features that you must be extra keen on for you to make the best buy:

Magnification

This is the first crucial feature you have to look for when shopping for a scope. You have to choose the magnification power of the scope according to the range you intend to shoot. If you are looking for versatility, be sure to go for a scope that has a wide magnification range of about 2x-12x. However, you will have to give up a load of convenience as you will be adjusting the scope every often. Plus, you will have to put up with more weight, diameter, and length.

Therefore, it is advisable to just get a scope for the specific range you intend to shoot as it is much easier to swap scopes than adjust one all the time.

Objective lens diameter

If you want bright and crisp clear images, go for a scope that has a wide objective lens diameter. It allows more light in which results in brighter images especially when you are shooting in hazy and low-light conditions.

 

However, the larger the objective lens diameter the bigger and heavier the scope is. So, you have to find a balance and get what works for your situation. If you want a scope for hunting, you have to choose one that gives you the best images but also doesn’t way you down as you will be moving around a lot when stalking your prey.

Lens coating

10 Best Scopes for AR 10 - Reduce the Risk of Missing Your Target to the Minimum!

Almost all modern scopes have coated lenses. Lens coating is essential as it reduces glare and reduces the loss of light caused by reflection. This allows you to use the scope in bright light, low-light, and no-light conditions. Go for a scope with a fully multi-coated lens like the Nikon PROSTAFF P3 3-9×40 Riflescope above.

Type of optical glass used

Choose a scope with superior glass quality as it will allow you to see your target much easier and clearer at any magnification power setting. You can do a side-by-side comparison to pick the best.

Eye relief

This is usually overlooked as a minor consideration but it is actually very important especially if you intend to use your AR-10 frequently. Choose a scope that features an adjustable eye relief so that it is easier for you to make it comfortable to use.

If you go for a scope with a fixed eye relief, ensure it offers a generous one. It should fit you well right away and still be comfortable even at higher magnification settings.

Field of view

This is the area you can see in feet through your eyepiece at a certain distance, usually at every 100 yards. It corresponds with the magnification of the scope. At a higher magnification, the field of view is narrower and vice versa.
