Description
The Rise Armament RA-1012 Bolt Carrier Group is a complete .30-caliber bolt-carrier assembly for compatible AR-10 builds. Designed as a replacement or upgrade component, it supports .308 Winchester and 6.5 Creedmoor.
The assembly combines an individually magnetic-particle-inspected 9310 steel bolt with a heat-treated, case-hardened 8620 tool steel carrier. Its tool steel gas key is secured with Grade 8 hardened fasteners and properly staked.
Additional construction details include a 4140 steel cam pin and a shot-peened tool steel extractor. The complete bolt carrier group is precision manufactured and individually inspected.
A black nitride finish gives the steel assembly its black color and an easy-to-clean surface. This RA-1012 bolt carrier group is offered in New condition.
