Features

Proof's AR barrels are meticulously engineered to enhance performance and reliability within the AR platform. Their innovative Caliber Matched Gas System (CAMGAS) is specifically tuned for the cartridge and barrel length, ensuring optimal gas flow and operation. While the AR-15 platform was originally designed around the .223 Remington and 5.56 NATO cartridges and the AR-10 for the .308 Win/7.62 NATO, the introduction of higher performance cartridges like the .22 Nosler and 6.5 Creedmoor necessitated a redesign of gas port locations. By strategically relocating the gas port, Proof maintains consistent gas system pressure comparable to the original AR designs. This thoughtful adjustment results in a noticeably softer recoil impulse, reduced fouling in the receiver, enhanced extraction reliability and decreased wear on brass. Experience the improved efficiency and reliability that Proof's advanced barrel technology brings to your AR platform, ensuring a superior shooting experience with every shot.
