Proof Research designed this AR-15 barrel to improve performance and reliability for the AR platform. It is chambered in .223 Wylde, measures 16 inches, and includes a 5/8×24 threaded muzzle for commonly used muzzle devices. Constructed from stainless steel, the barrel incorporates Proof’s Caliber Matched Gas System (CAMGAS) to tune the gas timing for the cartridge and barrel length.
The CAMGAS approach helps deliver a softer recoil impulse, reduced fouling in the receiver, and more consistent extraction—benefits that support repeatable accuracy and dependable cycling in precision-oriented AR builds.
