LWRCI Advanced Combat Bolt 6.8 SPCii
Availability: Back Order.
Replacement bolt for any of our 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. 

Our Advanced Combat Bolt is an evolution in bolt design. With a fully supported bolt face, our 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. Machined out of a super-alloy formulated to take extreme loads without failure, our ACBs are 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 our SIX8 ACB the best choice for any 6.8mm SPC firearm.
