The heavy barrel features a 1:8 twist to perfectly stabilize all different grain weights of ammunition, so you can use the Ruger AR-556 for home defense, hunting, target shooting, or competition. One of the nicest features on this Ruger AR is that it ditches the A2 pistol grip in favor of a more ergonomic option that appears to be designed to actually fit a human being's hands. The chamber accepts both 556 NATO and 223 Remington ammo, so you can shoot whatever ammo you can get your hands on.Sturm, Ruger & Co., Inc. has been one of the nation's leading manufacturers of dependable rifles, shotguns, and pistols since 1949.
