Owner’s Manual,The AR-556® rifle with free-float handguard is now available chambered in .300 Blackout.

This addition to the Ruger® AR-556 rifle line features a 16.10″ 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.

The dust cover and metal magazine are marked with the caliber for easy identification of both the rifle 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.
