The Chrome Moly AR-15 HBAR contour barrels feature a gas port drilled for a .750 gas block. An indent is provided opposite the gas port to enable easy installation. Also included is an M4 barrel extension. These barrels accept muzzle devices with a 1/2x28 thread. Chambers are finished, but barrels should be headspaced and installed by a qualified gunsmith prior to use.
Include a headspaced BCM Bolt Assembly with your Criterion chrome-lined barrel. The BCM Bolt is MPI tested, includes tool steel machined extractor, BCM Extractor Spring and is shot peened for increased strength.
