Our core objective has been to enhance the performance and dependability of the AR platform through innovative barrel design. The incorporation of the caliber matched gas system (CAMGAS) has enabled us to meticulously fine-tune the gas system to accommodate 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 alternatives such as the 22 Nosler and 6.5 Creedmoor has resulted In increased bore pressure deeper into the barrel. By strategically adjusting port positions, we maintain the original gas system pressure of the AR platforms, resulting In reduced recoil, minimized receiver fouling, improved extraction reliability and decreased brass wear. This translates to heightened target accuracy and extended shooting sessions, all while taking full advantage of cutting-edge high performance cartridges.
