CMC proudly manufactures the highest quality firearms components in the industry. Carrier Assembly: The flared rear of the enhanced bolt carrier is designed to reduce carrier tilt/cant during recoil and increase reliability by strategically relocating key bearing surfaces. Made from Case-hardened 8620 steel. The CMC enhanced carrier has fewer points of contact, resulting in less friction area. The increase in mass ensures proper gas pressure and increases dwell time, thus improving extraction while shooting suppressed or short-barreled rifles (SBRs). Bolt Assembly: The Bolt is a "true" Mil-spec dimension. The external surfaces are CNC ground after heat treatment for a precision fit. The bolts are held to the highest possible tolerances. The "trumpet" area behind the gas rings, where carbon collects, is precision CNC Ground after heat treatment, to ensure as smooth of an area as possible, easing clean up and longevity. Made from 9310 Case Hardened Steel, bolt components are Shot Peened & Black Nitride coated. ### Features: - Black Nitride finish - Enlarged forward ports - Optimized for suppressor use - Hardened 4340 cam pin - Mil-Spec 8740 steel firing pin - MPI and HPT tested - Mil-Spec Extractor Spring & O-Ring - .308 and 6.5 Creedmoor compatible ** WARNING: This product contains chemicals known to the State of California to cause cancer, birth defects, or other reproductive harm.
