Product Description

What's in the Box

  • AR-556 300 Blackout Semi-Auto Optics-Ready Rifle with Free-Float Handguard
  • (1) 30-Round Magazine
  • Cable Lock
  • Owner's Manual

The AR-556® rifle with free-float handguard is now available chambered in .300 Blackout.

This addition to the Ruger® AR-556 rifle line features a 16.10" cold hammer-forged barrel with a 1:7" twist and pistol-length gas system to reliably function with both the lightest supersonic hunting rounds and heavy, subsonic rounds.

The rifle also boasts an 11" aluminum free-float handguard with Magpul® M-LOK® accessory attachment slots and a standard pistol grip for easy user customization.

The dust cover and metal magazine are marked with the caliber for easy identification of both the rifle and ammunition. The pistol-length gas system is tuned to run with a wide variety of ammunition, with or without a silencer. The 5/8"-24 muzzle threads are capped with a thread protector.

Firearm Features

  • 11" aluminum handguard is free-floated for accuracy and features Magpul® 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.
  • Flat top upper receiver features a Picatinny rail for easy attachment of magnified optic, red dot or open sights.
  • Made from 7075-T6 hard-coat anodized aluminum forgings, shot-peened and proof-tested 9310 steel bolt, and 8620 steel bolt carrier. The inside diameter of the carrier and gas key are chrome plated and the key is staked for longevity.
  • Single-stage trigger provides durable and reliable fire control. The enlarged trigger guard is designed to allow gloved shooting in cold weather.
  • Six-position, telescoping, M4-style buttstock and Mil-Spec buffer tube allow the rifle to be properly sized for different shooters or varying levels of outerwear.
  • Equipped with a heavy-contour, cold hammer-forged 4140 chrome-moly steel barrel with ultra-precise rifling provides exceptional accuracy, longevity and easy cleaning. M4 feed ramps provide improved reliability, and the matte black oxide finish reduces glare and provides corrosion resistance.
  • Ergonomic pistol grip features an extended trigger reach for more precise trigger control.
  • Made from aerospace-grade 7075-T6 aluminum forging, the flat top upper receiver features a forward assist, dust cover and brass deflector.
  • Also includes: one, 30-round metal magazine.

by Adam from Grandville, MI on April 23, 2020

Was a great transaction, A: I got a hell of a deal, thank you B: Ran through the ammo Flawlessly C: It also looks cool I'm having some sight issues but that's not the guns fault i'm thinking operator error. Gun is an absolute riot. i added a vert grip, angle irons, laser, and a red dot lol supressor and performance triggers would really make this ar top notch.
