LBE Unlimited AR-10 .308/7.62 Bolt Carrier Group

Trusted by new and experienced AR-10 builders and enthusiasts, the LBE Unlimited AR-10 .308/7.62 Bolt Carrier Group is a complete carrier group designed to ensure smooth cycling and consistent operation in any shooting application. The case-hardened billet 8620 steel carrier and Carpenter 158 steel bolt work together to deliver exceptional strength and stability under heavy recoil. A Mil-Spec phosphate finish maximizes protection against rust, corrosion, and wear, while the chrome-lined gas key and firing pin channel ensure smooth operation — even with dirty ammo — for improved longevity and consistency. Better yet, this American-made BCG features properly-staked gas key screws, engineered to offer additional strength and smooth cycling while eliminating the risk of the screws backing out or breaking for smooth performance and reduced wear. Includes forward assist serrations. Made in USA.
