Proof Research 16" Natural AR-Type Barrel - Unmatched Precision and Versatility - 101261

Our primary focus has been on advancing the performance and reliability of the AR platform by implementing innovative barrel designs. The introduction of the caliber matched gas system (CAMGAS) allows us to finely tune the gas system for each specific cartridge and barrel length. Although the AR-15 and AR-10 were initially designed for 223REM, 5.56x45mm and 308 win/7.62 NATO rounds, the addition 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 maintain the original gas system pressure of the AR platforms, resulting In reduced recoil, decreased receiver fouling, improved extraction reliability and less brass wear. This leads to enhanced target accuracy and extended shooting sessions while harnessing the capabilities of advanced high performance cartridges.
