Sons of Liberty Gun Works MK10/AR-10 .308 Bolt Carrier Group – Hard Chrome - 308BCGMK10

The Sons of Liberty Gun Works .308 bolt carrier group is based on the same design as the 5.56 enhanced bolt carrier group only beefed up to withstand the higher pressures of the 7.62×51 cartridge. The carrier is made from 8620 steel and comes with all the same enhancements. This SOLGW 308 BCG features the modified cam pin path, which helps to increase dwell time for more reliable extraction. It also has a modified gas port for directing gas around the bolt tail more efficiently as well as an additional side gas port for directing excess gas away from the shooter. The carrier has multiple relief cuts to keep dirt and carbon from building up and causing reliability issues. The Sons of Liberty Gun Works AR-10 bolt carrier group will keep your rifle running reliably.

The SOLGW .308 bolt is machined out of a proprietary material with an extremely slick finish that is easy to clean. It features dual ejectors and an enhanced extractor to reliably eject spent shell casings from the rifle. The extractor utilizes two springs in a “lobster tail” shape that increases strength and doesn’t wear as quickly as single spring extractors. This .308 BCG will make a great addition to your next build.
