Ruger Ar-556 5.56x45mm 16.10 inch 30+1 Hardcoat Anodized Finish

The Ruger AR-556 rifle brings the AR-15 platform into a hard-use-ready package with a 16.10" cold hammer-forged heavy barrel (1:8" twist, 5 grooves) chambered in 5.56 NATO that stabilizes bullets from 35×77 grains and accepts both 5.56 NATO and .223 Rem., while the 1/2"-28 threaded muzzle lets you attach brakes or suppressors as needed for range, hunting, or duty use. The flattop upper receiver is machined from 7075-T6 forging with a Picatinny rail for optics and open sights, and the free-float 11" aluminum handguard features Magpul M-LOK slots at 3, 6 and 9 o—clock for lights and grips without disturbing barrel harmonics, aiding accuracy at distance. Ruger's durable Type III hard coat anodized finish, chrome-plated BCG internals, shot-peened 9310 bolt, and staked gas key deliver long service life and reliable cycling during high-round strings; the single-stage trigger and ergonomic polymer grip aid consistent trigger control, and the six-position collapsible synthetic stock lets shooters of different sizes or in cold-weather layers get a consistent cheek weld and length of pull. Weighing about 6.7 lb and measuring 32.25"×35.50" overall, the AR-556 is an optic-ready semi-auto rifle suited to tactical training, varmint or predator hunting, and practical range work; FFL transfer required.
