LWRC Advanced Combat Bolt for 6.8 SPC

The LWRC Advanced Combat Bolt (brand part number 2000070A01) is a replacement bolt built for any LWRC rifle chambered in 6.8mm, covering both the Six8 line and the legacy M6 rifles running 6.8 SPC barrels. LWRC machines the ACB from a super-alloy formulated to handle extreme loads without failure, then shot-peens the bolt for extra durability before applying a nickel-boron coating that increases strength and lowers the coefficient of friction. The bolt fits into any Mil-STD carrier and functions accordingly, so it drops into existing 6.8mm-pattern bolt carrier groups without modification. A fully supported bolt face and a dual-spring extractor design set this bolt apart, eliminating the extractor pocket undercuts that weaken traditional bolts while increasing extraction force and roughly tripling service life.
