Product Description

What's in the Box

  • Ruger AR-556 5.56mm Semi-Automatic Pistol
  • (1) 30-Round Magazine
  • Cable Lock
  • Owner's Manual

The all new AR-556® pistol is equipped with an SB Tactical® SBA3™ Pistol Stabilizing Brace®, which features integral QD sling sockets and a minimalist design. This pistol also boasts a carbine-length gas system for reliability. The 9" aluminum free-float handguard features Magpul® M-LOK® accessory attachment slots for easy customization.

The AR-556 pistol ships with one 30-round Magpul PMAG.

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.
  • Carbine-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. The 1:8" twist rate stabilizes bullets from 35 to 77 grains, and the 5.56 NATO chamber allows the use of both 5.56 NATO and .223 Rem. ammunition. 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.
  • A Ruger® flash suppressor is provided, and the 1/2"-28 threaded barrel allows for standard muzzle accessories to be installed.
  • Also includes: One, 30-round Magpul® PMAG®.

(5 out of 5) Ruger 556 pistol
by from Marysville, MI on

I purchased this in spring 2018. Best price from Sportsman's Outdoor Superstore. I have another full size AR but I shoot the Ruger 556 pistol more then the others. It's a blast to shoot. Iron sites with red dot. Very accurate to 75 yards. Still hitting steel target at 100 yards. You will not regret buying this pistol. 

(5 out of 5) Love this firearm!
by from Knoxville, TN on

This is my first AR. I was skeptical to say the least about getting a shorter AR. Several people at gun stores discouraged me from getting one. It was between the Saint Victor, and this one. They both were very close in overall length, so I went with the Ruger.
 I’m glad I did, the extra 3” of barrel proved to be a good choice. I would recommend this gun to anyone. You can’t beat the price, this is one of those rare instances where I got more than I paid for.

(5 out of 5) Ruger Quality + Excellent Value!
by from Tempe, AZ on

Ruger has created a winner! This is an excellent entry level AR pistol with all of the basic features in an AR pistol. The SB Tactical SBA3 brace is excellent. Placed a Vortex SPARC AR red dot and had it dialed in after a few rounds. Fired several hundred rounds of brass and a couple hundred steel cased rounds without any issues.
 The only item I personally upgraded was the grip. This pistol is an excellent value and defines Ruger quality!

(5 out of 5) My first AR Pistol
by from Georgetown, TX on

I have several AR rifles, but this is my first AR pistol. Couldn't pass it up for the price, especially with the SB stabilizing brace. Cleaned and lubed it and took it to the range and fired 110 rounds through it without any problems.
 Half Fiocchi 55gr fmj and half Federal AE 55gr fmj. I only shot it at 50 yards, but with the Primary Arms red dot, I was able to shoot 1¼ groups from a rest. Not bad for an old man with astigmatism.

(5 out of 5) Really great pistol
by from Soddy-Daisy, TN on

Purchased this pistol sight unseen and it is really great. I liked it so much that I just purchased 2 more of them. I did do a lot of research on them before I made this purchase and I could not find any negative comments about it at all.
 Ruger has been around a long time and I expect that this pistol will be too. Sportsman's Outdoor Superstore does a wonderful job of shipping it when they say they will and the receiving FFL folks had no problems. Will purchase from them again if I ever have enough money after this 2nd purchase.

(5 out of 5) Great dealer, Great product
by from Cottage Grove, OR on

Very satisfied with my new pistol and the customer service I experienced.
