Proof Research AR-Type Barrel 16" for AR-Style - Stainless Steel - 128664

Our primary focus has been on elevating the performance and reliability of the AR platform through innovative barrel design. We've achieved this by introducing the caliber matched gas system (CAMGAS), which allows us to precisely adjust the gas system for each cartridge and barrel length. While the AR-15 and AR-10 were initially designed for 223REM, 5.56x45mm, 308 win/7.62 NATO rounds, the introduction of higher-performance options like the 22 Nosler and 6.5 Creedmoor has resulted In increased bore pressure further down the barrel. To address this, we've strategically repositioned the ports to maintain the original gas system pressure of the AR platforms. This, In turn, leads to reduced recoil, minimized receiver fouling, improved extraction reliability, less wear on brass casings. The end result is a notable enhancement In target accuracy and extended shooting sessions, all while harnessing the capabilities of cutting-edge, high performance cartridges.
