Smyth Busters: AR-10 vs AR-308 - What's the Difference?
This video from Brownells Gun Techs Caleb and Steve clarifies the distinction between the AR-10® and the generic AR-308 platform. They emphasize that the AR-10® is a specific, trademarked rifle by Armalite, while AR-308 is a common designation for other rifles chambered in 7.62 NATO or .308 Winchester. The core of the discussion revolves around parts interchangeability, highlighting significant differences in upper receivers, barrel extensions, and handguard mounts between the two. While some components like fire control groups, dust covers, and magazines are compatible, it's crucial for owners to understand these distinctions to avoid compatibility issues, especially when purchasing aftermarket parts.
