Description
The All-Rounder Carbine Bolt Carrier Group (ARC BCG) is our individually proof tested and mag particle inspected bolt with an inner diameter bolt run that is machined tighter than competitor offerings. This gives the bolt a “Just Right” gas seal inside of the carrier which increases gas efficiency and service life. Nearly all M16 BCG manufacturers do not compensate for the lack of chrome plating in a TDP bolt carrier, but we make up the difference with our tight tolerance machining.
Our bolt is shot-peened Crucible Carpenter 158®, and individually proof tested to guarantee service life. Our machined, chrome lined gas key is sealed against the carrier with Permatex gasket sealant and is affixed with our OCKS fasteners at 53 in/lbs w/thread locker. Our extractors are billet machined 4140 and manganese phosphate coated to retain grip against the casing rim, and utilize genuine Sprinco 5 coil extractor springs with rubber insert for added reliability and service life.
