Understanding Caliber in the AR Platform
What is Caliber?
In firearms terminology, caliber refers to the diameter of the bullet or the bore of the gun barrel. It is a critical measurement that influences everything from accuracy to stopping power. The AR platform is capable of accommodating a wide range of calibers, from small rimfire rounds to massive big-bore cartridges.
AR-15 vs. AR-10
Before we dive into the specifics of large-caliber options, it's essential to differentiate between the AR-15 and the AR-10 platforms. The AR-15 is typically chambered for lighter cartridges like the 5.56 NATO, while the AR-10 is designed for larger rounds such as the .308 Winchester. However, both platforms can be adapted for a variety of calibers, opening the door to big-bore options.
The Rise of Big-Bore ARs
The advent of big-bore AR rifles has transformed the landscape of tactical firearms. While traditional AR-15s are excellent for target shooting and varmint hunting, larger calibers provide a new level of power and versatility. This has made them popular among hunters, tactical enthusiasts, and those interested in personal defense.
