Product Description

What's in the Box

  • Ruger AR-556 5.56mm Flat Dark Earth
  • (2) 30-Round Magazines
  • Cable Lock
  • Owner's Manual

The Ruger AR-556 FDE (Flat Dark Earth) Magpul M4 Carbine is made from aerospace-grade 7075-T6 aluminum forging; the flattop upper receiver includes a forward assist, dust cover and brass deflector, and is Type III hard coat anodized for maximum durability. The Flat Dark Earth Magpul furniture includes a six-position telescoping MOE carbine buttstock, an MOE M-Lock handguard, and an MOE AR15 grip.


AR-556 Features

Windage Adjustable Ruger Rapid Deploy Rear Sight: 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.
Forged 7075-T6 Aluminum Upper Receiver: Made from aerospace-grade 7075-T6 aluminum forging, the flattop upper receiver includes a forward assist, dust cover and brass deflector, and is Type III hard coat anodized for maximum durability.
Shot Peened, 9310 Alloy Steel Bolt: The bolt is machined from 9310 alloy steel and is shot peened and pressure (proof) tested to ensure strength, structural integrity and durability.
Patent Pending Barrel Nut and Delta Ring: The patent pending Barrel Nut and Delta Ring are designed for one person handguard removal and installation. The design accepts standard carbine length handguards. The barrel nut uses a standard wrench and can be swapped with a Mil-Spec barrel nut if desired.
Elevation Adjustable Front Sight: 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.
Medium Contour Cold Hammer-Forged Barrel: The 16.10 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 1/2-28 threaded barrel allows for standard muzzle accessories to be installed.
Single Stage Trigger and Enlarged Trigger Guard: The single stage trigger provides durable and reliable fire control. The enlarged trigger guard is designed to allow for gloved shooting.
Matte Black Oxide Bolt Carrier with Staked Gas Key: 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.
Serrated Face Milled Gas Block: 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.

(5 out of 5) Great
by from Godley, TX on

Finally shot today, sight in a Sig Romeo 5 on top, both were flawless, both bought here...sat and watched my buddies adjust their gas blocks and $700 scopes on $2k built rifles while this rig was zeroed within 4 and never failed.

(5 out of 5) Best deal on a great gun
by from Blue Springs, MO on

Awesome price with all the Magpul extras, plus an extra mag! Did a lot of research and found Sportsman's was by far the best value. My new go to gun store.

(5 out of 5) No complaints here
by from Charlotte, NC on

Great fun, fun to shoot, and a great value for the price. For those that don't know, the FDE color is a little darker than it appears in the picture here. Definitely recommend SOSS. Have bought multiple guns from them, and will buy more.

I bought my ar 2 days before the 2016 election i thought Hillary was going to win. I'm in no way an AR15 connoisseur, but I love it. It shoots perfectly and accurate. I'd recommend it to anyone. SOSS is awesome to deal with and has the best prices!

by from New Bern, North Carolina on

Just picked up and I'm very pleased, I've not yet fired it but did all the research and watched UTubes test videos and ratings, therefore gave performance a 5. The price was unbeatable, the package arrived in excellent condition no damage to the box everything was complete and organized. My first sport rife, could not beat the experience. Thanks Sportsmans Outdoors keep up the good work. AMR.
