Ruger's AR-556 is made from 7075-T6 hard-coat anodized aluminum forgings, shot-peened and proof-tested 9310 steel bolt and 8620 steel bolt carrier. Its barrel nut and delta ring allow easy, one-person service of the heat-resistant glass-filled nylon handguard. The design accepts most standard carbine-length handguards. Handguards are made from heat-resistant glass-filled nylon for shooting comfort and durability. Rapid Deploy folding rear sight provides windage adjustability and pairs with the A2-style, F-height, elevation-adjustable front sight for a solid, reliable aiming system. The AR-556 features a six-position, telescoping, M4-style buttstock and Mil-Spec buffer tube; cold hammer forged alloy barrel and ergonomic pistol grip with an extended trigger reach for more precise trigger control. Includes 30rd Magpul PMAG and front sight tool.
