Connecticut-based Ruger is adding to their AR556 series rifles with the introduction this week of a model chambered for the popular .300 AAC Blackout cartridge.
While Ruger’s AR556 rifle has only previously been offered in .223/5.56-caliber models, and in the AR556 MPR line in .350 Legend and .450 Bushmaster, the Blackout variant is new. Featuring a 16.10-inch cold hammer-forged barrel with a 1-in-7 twist, the new offering has a pistol-length gas system “to reliably function with both the lightest supersonic hunting rounds and heavy, subsonic rounds.”
The rifle also comes standard with an 11-inch aluminum free-float handguard with Magpul M-LOK accessory slots. Suppressor ready, the rifle has 5/8-24TPI muzzle threads capped with a thread protector. In the interest of keeping the user in the right ammo state of mind, both the dustcover and the magazine are marked with the caliber.
The overall length is 33-inches with the six-position M4 style stock fully collapsed and 36.25 with it fully extended. Weight is 6.4-pounds.
