Proof Research 16" Natural AR-Type Barrel - Unmatched Precision and Versatility - 100561

We've been dedicated to enhancing AR platform performance and reliability through innovative barrel design. The caliber matched gas system (CAMGAS) enables precise gas system tuning for various cartridges and barrel lengths. Originally optimized for 223REM, 5.56x45mm and 308 win/7.62 NATO, the AR-15 and AR-10 now accommodate higher-performance options like the 22 Nosler and 6.5 Creedmoor. Strategic port repositioning maintains the original gas system pressure, leading to reduced recoil, minimized receiver fouling, enhanced extraction reliability and reduced brass wear. This results In improved target accuracy and extended shooting sessions with cutting-edge high performance cartridges.
