Proof Research 18" Natural AR-Type Barrel - Optimal Precision and Performance - 100448

Our focus has been on enhancing the AR platform's performance and dependability through innovative barrel design. The caliber matched gas system (CAMGAS) has enabled us to finely tune the gas system according to each cartridge and barrel length. While the AR-15 and AR-10 were initially optimized for 223REM, 5.56x45mm and 308 win/7.62 NATO rounds, the introduction of higher-performance options like the 22 Nosler and 6.5 Creedmoor has LED to increased bore pressure further along the barrel. Through strategic port repositioning, we maintain the original gas system pressure of the AR platforms, resulting In reduced recoil, minimized receiver fouling, enhanced extraction reliability and reduced brass wear. This translates to improved target accuracy and prolonged shooting sessions, all while harnessing the capabilities of cutting-edge high performance cartridges.
