Ruger® AR-556® 5.56 NATO/.223 Rem. Semi-automatic Rifle

The AR-556 has been wildly popular since its inception—and for good reason. It's fun to shoot, highly affordable, easily customizable, and ultra-reliable. Ruger’s AR is built around forged 7075-T6 aluminum upper and lower receivers, and features a cold hammer-forged, chrome-moly steel barrel capped with Ruger’s own highly effective muzzle device. The AR-556 features a 1:8” twist that excels with a wide range of rounds—from 35 to 77 grains—so it offers a greater degree of versatility than other twists. This model comes with the improved free-float M-LOK handguard.

  • Forged 7075-T6 aluminum upper (type III hardcoat-anodized) with forward assist, dust cover and brass deflector
  • Forged 7075-T6 aluminum lower with Type III hardcoat-anodized finish
  • Free-floating M-LOK handguard will not affect accuracy as it does not touch the barrel
  • Single-stage trigger provides durable and reliable fire control
  • Ergonomic pistol grip features an extended trigger reach for more precise trigger control
  • 1:8" twist rifling provides versatility for bullets from 35 to 77 grains
  • Shot peened, 9310 alloy steel bolt
  • Barrel is threaded (1/2"-28)
  • Includes 30-rd. Magpul® PMAG magazine
