LBE Unlimited AR-15 5.56 NATO Bolt Carrier Group

The LBE Unlimited AR-15 5.56 NATO Bolt Carrier Group is a complete, drop-in BCG designed to ensure smooth and consistent operation in any tactical, target, or defensive shooting application. The phosphate-coated 8620 steel carrier and the Carpenter 158 bolt offer exceptional strength and stability under heavy recoil. The chrome-lined carrier interior and gas key protect against rust, dirt, and carbon buildup — 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 also eliminating the risk of the screws backing out or breaking for smooth performance and reduced wear. Includes extractor and bolt gas rings. Made in USA.
