LWRC 200-0070A01 Advance Combat Bolt Action Rifle 6.8 SPC Alloy

The LWRC Advanced Combat Bolt is an evolution in bolt design. With a fully supported bolt face, the ACB lacks the two undercuts on either side of the extractor pocket that weaken traditional bolts. In addition, the extractor utilizes a dual-spring design that increases extraction force and triples the service life. Machined out of a super-alloy formulated to take extreme loads without failure, the ACB is also shot-peened for extra durability. A nickel-boron coating increases strength and lowers the coefficient of friction. All of these factors and more make a Six8 ACB the best choice for any 6.8mm SPC firearm. Note: Replacement bolt for any of LWRC rifles chambered in 6.8mm, including both the Six8 and legacy M6 platforms as well as the .224 Valkyrie. This bolt fits into any Mil-STD bolt carrier and functions accordingly.
