Ruger® AR-556® .300 AAC Blackout Semi-automatic AR-15 Rifle

The .300 AAC Blackout round was developed to provide superior ballistic performance at standard engagement ranges vs. 5.56 NATO while also functioning flawlessly with a suppressor—all while utilizing standard M4 receivers, bolts and magazines. And now, Ruger has adapted their AR-556 platform to take full advantage of the .300 AAC Blackout.

Ruger’s AR is built around forged 7075-T6 aluminum upper and lower receivers, and features a heavy-contour, cold hammer-forged steel barrel with ultra-precise rifling that provides exceptional accuracy, longevity, and easy cleaning. 11" aluminum handguard is free-floated for accuracy and features M-LOK accessory attachment slots along the 3:00, 6:00 and 9:00 positions, with additional slots on the angled faces near the muzzle. Finished off with a single-stage trigger and ergonomic pistol grip, the AR-556 is the ultimate .300 AAC Blackout Rifle.

  • 16.1" cold hammer-forged heavy barrel with 5/8x24 threads
  • 11" free-float aluminum handguard with M-LOK slots preserves accuracy and provides a rigid platform for accessories
  • Flat top upper receiver features a Picatinny rail for easy attachment of magnified optic, red dot or open sights
  • Single-stage trigger provides durable and reliable fire control
  • Enlarged trigger guard is designed to allow gloved shooting in cold weather
  • Ergonomic pistol grip features an extended trigger reach for more precise trigger control
  • Shot-peened and proof-tested 9310 steel bolt, 8620 steel bolt carrier
  • Includes (1) 30-rd. magazine
