LWRC Advanced Combat Bolt NiB 6.8 SPC / .224VAL

LWRC International  Advance Combat Bolt Features:

This Advanced Combat Bolt is a replacement bolt for any of LWRC rifles chambered in 6.8mm SPC, including both the Six8 line and the legacy M6 rifles as well as rifles chambered in .224 Valkyrie. This bolt fits into any Mil-STD carrier and functions accordingly. The bolt features a fully supported bolt face, and to improve durability LWCR’s ACBs lack 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. The bolt is machined out of a super-alloy formulated to take extreme loads without failure, they are also shot-peened for extra durability. This high quality replacement bolt is finished with a nickel-boron coating which increases strength and lowers the coefficient of friction. All of these factors and more make the Six8 ACB the best choice for any 6.8mm SPC or .224 Valkyrie firearm.
