LWRC 2000070A01 Advance Combat Bolt LWCR Rifles 6.8 SPC Alloy

This replacement bolt for any of LWRC rifles chambered in 6.8mm including both the Six8 line and the legacy M6 rifles with 6.8 SPC barrels. This bolt fits into any MilSTD carrier and functions accordingly. With a fully supported bolt face LWCRs ACBs lack the two undercuts on either side of the extractor pocket that weaken traditional bolts. In addition the extractor utilizes a dualspring design that increases extraction force and triples the service life. Machined out of a superalloy formulated to take extreme loads without failure they are also shotpeened for extra durability. A nickelboron coating increases strength and lowers the coefficient of friction. All of these factors and more make our Six8 ACB the best choice for any 6.8mm SPC firearm.
