Ruger has announced a new AR-556 Pistol chambered in .300 Blackout. 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.
