The Bootleg four-position adjustable bolt carrier for the AR-308 lets you tune your rifle’s gas system at the carrier instead of at the gas block. It is CNC machined from S7 tool steel and chrome lined for strength and wear resistance. A precision detent holds one of four gas settings, so you can set the system for an unsuppressed rifle or a suppressed build. The result is a way to fine-tune system timing for reliability and recoil comfort while extending the life of the bolt carrier group.
