LanTac USA LLC .308 Enhanced Bolt Carrier Group – Black Nitride

The LanTac .308 Enhanced Bolt Carrier Group delivers reliability improvements over standard mil-spec carriers for AR-10 and .308 AR-pattern rifles. Designed for higher-pressure cartridges and sustained fire schedules, this BCG features enhanced gas key staking, improved cam path geometry, and a tool steel extractor for consistent extraction under adverse conditions.

Finished in black nitride for hardness and corrosion resistance, the carrier surface resists carbon buildup and simplifies cleaning. The bolt is MPI and HPT tested. Installation is drop-in for any mil-spec .308 AR upper receiver—no fitting or gunsmithing required. Includes enhanced extractor spring and black insert.
