Ruger AR-556 Freefloat Handguard 223Rem/5.56NATO 16.1″ Barrel 30+1




The Ruger AR-556 Freefloat is a rock solid, affordable AR15 with a 16.10″ cold hammer forged, freefloated barrel and M-Lok handguard. Beginning with the solid foundation of forged 7075-T6 aluminum upper and lower receivers, the AR-556 makes use of a shot-peened and proof-tested 9310 steel bolt, and 8620 steel bolt carrier for strength and durability. The inside diameter of the carrier and gas key are chrome plated to resist corrosion and the key is staked for longevity. A Carbine length gas system improves balance and reliability. The heart of the AR-556 is an accurate, medium contour, cold hammer-forged threaded barrel with 1:8″ twist and 5 grove rifling with M4 feed ramps and topped with a 1/2″-28 Ruger® flash suppressor. This optic ready rifle comes with a full length Picatinny rail with ample room for your choice of iron sights or optic. The 13″ Ruger freefloat handguard has large cutouts to save weight and improve cooling, and features M-Lok compatible accessory slots. Out back, a six-position, telescoping, M4-style buttstock allows the rifle to be properly sized for different shooters or varying levels of outerwear. An ergonomic Ruger grip provides a secure purchase and an enlarged trigger guard surrounds a single stage trigger. Other standard features include a brass deflector and dust cover. One (1) 30 round magazine included.
