The Ruger AR-556 is a standard gas impingement operated AR15 platform rifle featuring a milled gas block, located at a carbine-length (M4) position for improved balance and handling. Multiple attachment points include a QD socket and bayonet lug, for many sling and accessory mounting options. The AR-556 comes equipped with the Ruger Rapid Deploy folding rear sight which provides windage adjustability, and pairs with the elevation adjustable front sight for a solid, reliable aiming system. The six-position telescoping M4-style buttstock and Mil-Spec buffer tube allow the rifle to be properly sized for different shooters or varying levels of outerware or defensive gear. Made from aerospace-grade 7075-T6 aluminum forging, the flattop upper receiver includes a forward assist, dust cover and brass deflector, and is Type III hard coat anodized for maximum durability. The medium contour cold hammer-forged barrel with ultra-precise rifling provides exceptional accuracy, longevity, and easy cleaning. The 1:8″ twist rate stabilizes bullets from 35 to 77 grains, and the 5.56 NATO chamber allows the use of both 5.56 NATO and .223 Rem. Ammunition. M4 feed ramps provide improved operational reliability, and the matte black oxide finish reduces glare and provides corrosion resistance. A Ruger flash suppressor is provided, and the 1/2″-28 threaded barrel allows for standard muzzle accessories to be installed.
