The .308 barrel is a foundational component in the firearms industry, widely recognized for its versatility in both hunting and tactical applications. As a key part of the firearm’s anatomy, it determines accuracy, range, and overall performance. While the .308 round is larger than the typical AR-15 caliber, many modern firearm platforms, including some AR-10 variants, utilize this powerful caliber, bridging the gap between traditional hunting rifles and tactical firearms.
