Proof Research AR-Type Barrel 16" for AR-Style - Performance in Black - 128657

Our primary focus has been on elevating the performance and reliability of the AR platform by introducing innovative barrel designs. We've achieved this through the development of the caliber matched gas system (CAMGAS), which allows us to finely calibrate the gas system to match each cartridge and barrel length precisely. Initially designed for 223REM, 5.56x45mm, 308 win/7.62 NATO rounds, the AR-15 and AR-10 platforms have seen an expansion to include higher-performance options like the 22 Nosler and 6.5 Creedmoor. As these high performance cartridges generate increased bore pressure further down the barrel, we've strategically repositioned ports to maintain the original gas system pressure of the AR platforms. This strategic adjustment has resulted In several benefits, including reduced recoil, minimized fouling within the receiver, improved extraction reliability, decreased wear on brass casings. The ultimate outcome is improved target accuracy and longer-lasting shooting sessions, all while taking full advantage of cutting-edge high performance cartridges.
