Proof Research AR-Type Barrel 11.50" for AR-Style, Natural - 100394

Our primary focus has been on elevating the performance and reliability of our AR platform through revolutionary barrel design. Our groundbreaking caliber matched gas system (CAMGAS) has empowered us to precisely calibrate the gas system for each cartridge and barrel length. Originally optimized for 223REM, 5.56x45mm, 308 win/7.62 NATO rounds, the AR-15 and AR-10 platforms faced new challenges with the introduction of high performance options like the 22 Nosler and 6.5 Creedmoor. These cartridges generated increased bore pressure further down the barrel. However, we've countered this by strategically repositioning ports to maintain the original gas system pressure of the AR platforms. The result, reduced recoil, minimized receiver fouling, enhanced extraction reliability, decreased brass wear. This translates into improved target accuracy and extended shooting sessions, all while harnessing the capabilities of cutting-edge high performance cartridges. Experience superior AR performance with our innovative barrel design and CAMGAS technology.
