Superior Stainless Performance - Proof Research 12.50" AR-Type Barrel for AR-Style Rifles - 100530

Our central objective has been to enhance the performance and reliability of the AR platform through innovative barrel design. The caliber matched gas system (CAMGAS) has provided us with the capability to finely calibrate the gas system for each specific cartridge and barrel length. Although the AR-15 and AR-10 were originally designed 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 down 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 ultimately leads to improved target accuracy and prolonged shooting sessions, all while harnessing the capabilities of state-of-the-art high performance cartridges.
