The second addition to the Ruger® AR-556 Pistol line features a 10.50" cold hammer-forged barrel with a 1:7" twist and pistol-length gas system to reliably function with both the lightest supersonic hunting rounds and heavy, subsonic rounds.

This new .300 Blackout model is equipped with an adjustable SB Tactical® SBA3™ Pistol Stabilizing Brace® that features a minimalist design and integral QD sling sockets. The pistol also boasts a 9" aluminum free-float handguard with Magpul® M-LOK® accessory attachment slots for easy user customization.

The dust cover and metal magazine are marked with the caliber for easy identification of both the pistol and ammunition. The pistol-length gas system is tuned to run with a wide variety of ammunition, with or without a silencer. The 5/8"-24 muzzle threads are capped with a thread protector.
