Ruger

Ruger's AR-556 semi-automatic rifle is made from forged aerospace-grade 7075-T6 aluminum. The hard coat anodized, flattop upper receiver includes a forward assist, dust cover and brass deflector, while the Magpul MOE M-Lok handguards are made from heat-resistant glass-filled nylon. The Rapid Deploy folding rear sight provides windage adjustability and the front sight post is elevation adjustable, and includes a front sight tool. The A2-style F-height allows co-witness with many optics. It has a carbine-length, milled gas block with multiple attachment points for a QD socket, bayonet lug, and sling. Serrations on the angled face of the gas block provides a low-glare surface. It also has a bolt machined from 9310 alloy steel, single-stage trigger, chrome-plated bolt carrier with a matte black oxide finish on the exterior, and patent pending barrel nut and Delta ring for one person handguard removal and installation. The AR-556 also utilizes a heavy contour, cold hammer-forged barrel with a Ruger flash suppressor, ergonomic pistol grip and single-stage trigger. This CA compliant model is equipped with Juggernaut Tactical's fixed magazine kit, which disables the magazine release, and a Magpul MOE Carbine buttstock and Mil-Spec buffer tube.
