AR-556 Standard

"This rifle features a flip-up rear sight with windage adjustability, paired with an A2-style, elevation-adjustable front sight for reliable aiming. Made from 7075-T6 hard-coat anodized aluminum, it includes a proof-tested 9310 steel bolt and an 8620 steel bolt carrier with a chrome-plated interior and staked gas key for durability. The carbine-length gas block enhances balance and handling, offering multiple attachment points, including a QD socket and bayonet lug. Equipped with a cold hammer-forged alloy barrel with a 1:8"" twist rate, it ensures accuracy with 5.56 NATO and .223 Rem. ammunition. The barrel and flash suppressor feature a matte black oxide finish for glare reduction and corrosion resistance. Additional features include a six-position M4-style buttstock, ergonomic pistol grip, enlarged trigger guard, and single-stage trigger. The flat-top upper receiver has a forward assist, dust cover, and brass deflector. One 30-round Magpul PMAG magazine is included."
