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.

(4 out of 5) Good Budget AR
by from Londonderry, NH on

I purchased this rifle from Sportsman’s Outdoors in February 2020 ,on sale for $539.00. This is a no frills weapon Does not come with iron sights however for the money it is good quality. I threw a Holosun green dot on it and some angled after market backup sights. I did have some pretty serious cycling issues with a cheap brand of supersonic loads but I believe it was due to poor quality of the ammo more than any defect with the rifle as it has over 2000 rds of some decent subsonic rds through it without any issues . Overall a great entry level Ar platform at a great price

(4 out of 5) Black beauty
by from Grandville, MI on

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.

(4 out of 5) A good rifle with some lower quality aspects.
by from Springfield, MO on

The rifle has a very stiff trigger. I am guessing 7-9lbs trigger pull. The coating on the shell deflector has worn to show metal after 100 rounds. It works as it should but expect a trigger upgrade in the future. I won't recommend against it however I expected better quality from a Ruger. 4 stars.
