The .308 Bolt Carrier Group (BCG) is a cornerstone in the firearms sector, specifically engineered for the potent .308 cartridge. Integral for reliable ammunition cycling, it assures consistent firing and cartridge extraction. While the .308 is chiefly associated with the AR-10 platform, the BCG’s design and function principles remain analogous to the AR-15, ensuring that firearms enthusiasts get top-tier performance in both tactical and hunting scenarios.
