Proof Research Carbon AR .22 ARC Threaded Barrel 16" 1-7 Twist 5/8-24

Proof Research Carbon AR .22 ARC threaded rifle barrel for the AR-15 platform.

The Caliber Matched Gas System (CAMGAS) tunes port location and gas system pressure specifically for the .22 ARC cartridge and barrel length. This is intended to produce a softer recoil impulse, reduce fouling in the receiver, improve extraction reliability, and reduce wear on brass.
