AR-STONER AR-15 Barrel 300 AAC Blackout 16" Heavy Contour 1:8" Twist Phosphate Pistol Length Gas Port

This AR-STONER 300 AAC Blackout Barrel is an excellent choice for upgrading the AR platform with a more potent, versatile cartridge while maintaining one of the AR's key advantages: high ammunition capacity. The 300 AAC Blackout squeezes 30 caliber firepower into the traditional AR-15 envelope, and is available in either subsonic or supersonic ammunition varieties to serve a multitude of purposes. All that is needed to harness the enhanced performance of the 300 Blackout is a simple barrel swap; the bolt, carrier, magazine and all other components remain the same as those used in a traditional 223 Rem/5.56 NATO rifle. This Chrome Moly Vanadium Steel Barrel features a 5/8"-24 threaded muzzle for easy installation of your preferred flash hider, muzzle brake and/or sound suppressor. The barrel's Gas Port position offers the best compromise for most shooters since it is compatible with the majority of supersonic and subsonic ammunition in suppressed or unsuppressed rifles.
