The second addition to the Ruger® AR-556 Pistol line features a 10.50" 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.

This new .300 Blackout model is equipped with an adjustable SB Tactical® SBA3™ Pistol Stabilizing Brace® that features a minimalist design and integral QD sling sockets. The pistol also boasts a 9" aluminum free-float handguard with Magpul® M-LOK® accessory attachment slots for easy user customization.

The dust cover and metal magazine are marked with the caliber for easy identification of both the pistol 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

  • Lower receiver is fitted with an adjustable SB Tactical® SBA3™ Pistol Stabilizing Brace® to aid in accuracy, balance and recoil management.
  • Handguard is free-floating for accuracy and the slim, 9" length provides enhanced ergonomics and support. Magpul® M-LOK® accessory attachment slots along the 3:00, 6:00 and 9:00 positions.
  • Made from aerospace-grade 7075-T6 aluminum forging, the flattop upper receiver includes a forward assist, dust cover and brass deflector.
  • Bolt is machined from 9310 alloy steel and is shot peened and pressure (proof) tested to ensure strength, structural integrity and durability.
  • Pistol-length gas system ensures reliable function with a wide variety of ammunition.
  • 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.
  • Bolt carrier and gas key have chrome-plated inside diameters to provide exceptional resistance to hot gases. The gas key is staked so that it will not loosen after extensive firing. A matte black oxide finish on the exterior of the bolt carrier provides corrosion resistance.
  • The 5/8"-24 threaded barrel with factory-installed thread protector allows for standard muzzle accessories to be installed.
  • Also includes: One, 30-round metal magazine.

(5 out of 5) 300

I love this rifle. Received it in 7 business days of order. The price went up over a 100 dollars. Just wish it came with sights and a muzzle brake.

(5 out of 5) Very good AR pistol for the money!
by from Oklahoma City, OK on

No joke, this AR pistol performs pretty good despite being cheaper compared to its competition. Shooting this AR pistol is satisfying, recoil is barely any higher than 5.56, the SB tactical brace is surprisingly good like an actual AR stock, and the MLOK free float handguard is a clean design.
 Although if you plan to modify the gun, I suggest you check the ATF rules since they are pretty sensitive/complicated when it comes to AR pistols. Other than that, I would recommend this gun to anyone who enjoys shooting or for home defense.

(5 out of 5) Awesome gun!
by from Davenport, IA on

Great gun. Can't beat it for the money. The fit and finish is also spot on. Shoots really well. Shipped fast as well!
