Best Rifle Scopes

for an AR-10
The AR-10 is a semi-automatic rifle platform that is similar in design to the popular AR-15, but is chambered for larger cartridges such as the .308 Winchester and 7.62x51mm NATO. The rifle is known for its accuracy, power, and modular design, which allows for easy customization and the ability to add accessories such as scopes, bipods, and muzzle brakes.
The key attachment we will be looking at today is the scope. Depending on how you use your AR-10, you could need a very different scope. Seeing as you can outfit an AR-10 for just about anything, there are way too many options out there for your optics, but Sportsmans has your back.
Common Uses For an AR-10
One of the most popular uses for the AR-10 is as a hunting rifle. The .308 Winchester cartridge is well-suited for taking down medium-sized game such as deer and hogs, and the rifle's accuracy and power make it a viable option for longer-range shots. If you are hunting under 300 yards, you will be fine with a 3-9x scope. If you are a western hunter, you may want a 16x scope to reach out over 500 yards.
Another common use for the AR-10 is in competitive shooting. The rifle's accuracy and modular design make it a popular choice for both long-range and tactical shooting competitions. Some competitions can reach out to 1000 yards, and if that is the case for you, you will want a scope that has around 30x magnification.
The AR-10 is also used by some law enforcement and military units as a designated marksman rifle (DMR). The rifle's accuracy and power make it well-suited for long-range engagements, and it can be used to engage targets at distances beyond the capabilities of a standard issue assault rifle. To stay versatile, these kinds of rifles will be well off with a 3-12x magnification.
Is a Red Dot, Variable, or Fixed Scope Best?
The choice between a red dot, variable, or fixed scope for an AR-10 rifle depends on the intended use and personal preference of the shooter. Realistically, you can have a variable scope mounted to your rifle and canted iron sights or a red dot attached on a picatinny rail. This would give you the right magnification at nearly every range.
A red dot sight, also known as a reflex sight, is a popular choice for close- to medium-range shooting. They offer a wide field of view, fast target acquisition, and are easy to use. They do not have magnification, so they are best for close-range shooting.
Variable scopes, on the other hand, offer adjustable magnification, which allows the shooter to engage targets at a variety of ranges. They are a good option for long-range shooting and hunting. They are more complex than red dot sights, but they offer more versatility.
A fixed scope has a set magnification and they are less complex than variable scopes. They are simple to use and are usually made specifically for AR’s, so they are worth looking at. Although, if you want your AR-10 to be a versatile rifle, restricting it to a single magnification isn’t the best idea.
Common Cartridges for an AR-10
The AR-10 is a semi-automatic rifle designed to chamber a variety of cartridges. Some of the most common cartridges (and their Sportsmans Recoil Score) that an AR-10 can be chambered in include:
- .308 Winchester (2.97 SRS): This is the most popular cartridge for the AR-10. It offers good accuracy, power, and range, making it suitable for a wide range of shooting applications, including hunting and long-range target shooting.
- .243 Winchester (2.16 SRS): This is a smaller cartridge than the .308, but it still offers good accuracy and range. It is a popular choice for hunting and target shooting with lighter recoil.
- 6.5 Creedmoor: This cartridge offers excellent accuracy and long-range performance, making it a popular choice for long-range target shooting and hunting.
- .338 Federal (3.33 SRS): This is a more powerful cartridge than the .308 and .243. It offers good accuracy and range, but it is more suited for hunting larger game and long-range target shooting.
- .260 Remington (2.5 SRS): Another cartridge that provides good accuracy and range. It is used for long-range target shooting and hunting.
- .224 Valkyrie (1.5 SRS): This is a cartridge that is designed to provide long-range accuracy and flat trajectory. It is suitable for long-range target shooting and varmint hunting.
It's important to note that these are only some of the cartridges available on an AR-10 platform and the AR-10 is not a standardized platform and different manufacturers may have different options for chambering, so it's always best to check with the manufacturer to see what cartridges are compatible with a particular model of AR-10.
To play it safe, you should get a scope with at least 3.5 inches of eye relief for your AR-10. This isn’t a hard thing to do, there are plenty of these scopes on the market. You just want to make sure that you have enough room to handle the larger cartridges your AR-10 could offer without looking like a coon for a few days after the shot. You will also want a well-made scope that can hold up to the recoil of a large caliber.
