An AR is a fine piece of equipment that has been around for more than fifty years. If you know anything about these guns, you know the “AR” actually stands for the original manufacturer’s name for the firearm: ArmaLite Rifle.
So what’s the difference in an AR-10 and an AR-15?
AR-10s vs AR-15s: Know Your History
When comparing these rifles, it helps to know a little history on the AR-10s. These guns were designed as a military rifle, but setbacks in securing military contracts meant the company needed to refine their design.
Enter AR-15s. Setbacks in securing contracts meant ArmaLite sold the patent to Colt. Colt mass-produced these guns and they finally became a standard-issue during the Vietnam War. Then, when the patents from Colt expired, other manufacturers began making their versions.
AR-10s vs AR-15s have a lot of similarities and interchangeable parts because the AR-15 was built based on the AR-10. They do have a few key differences.
Differences in AR10s and AR-15s
Caliber and Weight
The main difference when comparing these two rifles is the caliber. AR-10s traditionally utilize a .308 Winchester/7.62x51mm NATO, and AR-15s traditionally use a .233/5.56x45. This means the AR-10’s magazine walls are larger to house the larger rounds. This makes the AR-10 lower receiver and other key parts bigger than the AR-15s and means AR-10s are usually heavier.
What You Aim to Shoot
When thinking about AR-10s vs. AR-15s, don’t forget to consider what you want to use the gun for. If you need stopping power combined with long-range accuracy — to take down a charging boar, for example — an AR-10 with traditional chamberings will suit you slightly better.
If your main usage of the gun is at the range or for use in home self-defense, you’ll get similar accuracy with an AR-15 with the benefit of the lighter weight and recoil. Additionally, AR-15 ammunition is less expensive, making it a slightly more accessible weapon.
The versatility of these guns means you can design the ARs to shoot practically whatever you want. AR-10 rounds tend to excel in long-range shooting and AR-15s tend to win in the weight category.
