The AR-556 rifle has been one of the most popular offerings in the lineup of Sturm, Ruger & Company, Inc. firearms, thanks to the general popularity of the modern sporting rifle. In late 2019, Ruger rolled out a new model with a with free-float handguard and a new chambering in .300 BLK.

This new addition to the line of Ruger AR-556 rifles features a 16.1-inch cold hammer-forged barrel that has a 1:7-inch twist rate and pistol-length gas system designed to function reliably with everything from the lightest supersonic hunting rounds and heavy, subsonic .300 BLK rounds.

The rifle also has an 11-inch aluminum, free-float handguard with Magpul M-Lok accessory attachment slots and a standard pistol grip allowing the user to customize the rifle to their liking.

For safety's sake, 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 and the muzzle features 5/8-24 TPI threads that are capped with a thread protector.
