Russell K on Apr 15, 2019
is this semi automatic?
Elijah on Aug 20, 2018
BEST ANSWER: Yes this firearm is a semi-automatic. It re-chambers 1 available round from the magazine each time you squeeze the trigger and fire the existing round already in the chamber. This continues until all rounds from the magazine are expended, at which time the bolt locks to the rear.
does the ruger ar556 have a heat shield?
dennis on Aug 26, 2018
BEST ANSWER: Hand-guards are made from heat-resistant glass-filled nylon for shooting comfort and durability.
I see eye let on bottom receiver is there one on upper receiver for a sling?
William on Aug 20, 2018
BEST ANSWER: When I rec'd mine, there was a sling point at the butt and on the forearm.
I removed original forearm and replaced with a quad forearm.
I also purchased the one point sling unit which fits right behind the receiver. If you decide to install it, be very careful when you remove the stock. A very small spring will pop up and away if you are not careful.
A one point sling on this rifle is the best way to carry it,this weapon will hug your body whether right handed or a southpaw.
Is the lower made of metal or composite?
Timothy on Jul 17, 2018
BEST ANSWER: The Ruger AR-556 has a forged, anodized aluminum lower receiver.
Rear sight folds down any problems adding optic sights?
William on Aug 19, 2018
BEST ANSWER: Not at all. I added a Red Dot to the top of my upper receiver with no problem. I can still flip up my rear sight and use it through the optics if i had to.
Hello...anyone have issues with this gun and steel case ammo? Thanks.
Doug on Dec 30, 2018
BEST ANSWER: I've had the rifle for a couple of years and occasionally shoot the steel case TulAmmo and have had no issues. Highly recommend the Ruger AR...
An the rear sight be removed?
Martin on Jan 18, 2019
Can you change the hand guard?
mason on Mar 14, 2019
BEST ANSWER: Yes you can. The only limitation is not all free float handguards will fit without taking the sight post/gas block out. The answer is yes though.
Is 5.56 stamped on the barrel?
Gerson on Mar 6, 2019
BEST ANSWER: Mine is stamped "5.56 NATO" it is a proprietary barrel. You can't Pin a different gas block on if you wanted to.its not very customizable unless you want to use a clamp on. However it is a Ruger and built very well. I'd probably hold out and get the ruger ar556 MPR if I had it to do over. But if you are wanting this rifle with the front post site this is a fine functioning rifle.
Is this NY complient ?
Darin on Feb 20, 2019
Does the Ruger AR 556 use a direct gas impingement or does it use a piston impingement?
Dwight on Feb 9, 2019
BEST ANSWER: Ruger's AR-556 is a direct impingement AR with their SR-556 a piston driven AR at more than twice the cost. Clean the AR-556 regularly and it may last longer than a piston driven system.

Great rifle, great price, great company.
Great rifle right out of the box. Clean with minimal effort to sight in. Easiest gun purchase I've ever made, ordered it and picked it up the following day. Was in the store for maybe 15-20 minutes. Not sure I'll ever buy guns any other way.

Ruger AR 556 Review Video

Watch the video to review features and specs of the Ruger AR 556, and compare the AR 556 to the Ruger SR762 and Mini 14 rifles.


Ruger AR 556 Black AR 15 .223/5.56mm 16.1-inch 30Rd

GrabaGun customers can’t say enough about this Ruger AR 556 with a 30 round Magpul magazine. A great 223 sporting rifle at a great price, be sure to stock up on extra magazines and ammo.

Ruger AR-556 Review

I'm very satisfied with the purchase of my Ruger AR 556. GrabAGun had the best price in my area, I called around before I purchased, and no other competitors could come close in price. This is my first AR platform rifle and Ruger is a well-respected company that makes good firearms, this AR 556 makes 4 Ruger's that I have in my collection, so I'm a little bias toward Ruger. Even though it is thought of as a budget rifle I believe the quality is still there. Nice rifle you will like it.


Ruger AR-556 Features

  • The milled gas block is located at a carbine length (M4) position for improved balance and handling. Multiple attachment points include a QD socket and bayonet lug, for many sling and accessory mounting options. Serrations on the angled face of the gas block provide a low glare surface.
  • The handguards are made from heat-resistant glass-filled nylon for shooting comfort and durability.
  • The front sight post is elevation adjustable, and a front sight tool is included. The A-2 Style F-Height allows co-witness with many optics. The Ruger® Rapid Deploy folding rear sight provides windage adjustability and is a solid, reliable aiming system when coupled with the elevation adjustable front sight. The rear sight can be folded out of the way to make room for optics but can be instantly redeployed if needed.
  • The 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 or defensive gear.
  • The 16.1 inch medium contour barrel is cold hammer-forged providing ultra-precise rifling for 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 operational reliability and the matte black oxide finish reduces glare and provides corrosion resistance.
  • A Ruger® flash suppressor is provided and the ½"-28 threaded barrel allows for standard muzzle accessories to be installed.
  • The ergonomic pistol grip features an extended trigger reach for more precise trigger control. The enlarged trigger guard is designed to allow for gloved shooting.
  • The chrome-plated bolt carrier inside diameter and chrome-plated gas key inside diameter 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.
  • Includes one 30-round Magpul® PMAG® magazine.

Our prices can't be beat, so buy with confidence.
