Proof Research 20" Natural AR-Type Barrel for AR-Style Rifles - Precision Redefined - 100042

Our primary focus has been on elevating AR platform performance and reliability through innovative barrel design. The caliber matched gas system (CAMGAS) allows for precise gas system tuning tailored to different cartridges and barrel lengths. While the AR-15 and AR-10 were initially designed for 223REM, 5.56x45mm and 308 win/7.62 NATO, the introduction of higher-performance options like the 22 Nosler and 6.5 Creedmoor has increased bore pressure further down the barrel. By strategically repositioning ports, we preserve the original gas system pressure of the AR platforms, resulting In reduced recoil, minimized receiver fouling, improved extraction reliability and less brass wear. This translates to enhanced target accuracy and extended shooting sessions, all while harnessing the capabilities of advanced high performance cartridges.
