Product Description

What's in the Box

  • Ruger AR-556 Optic Ready Carbine Rifle
  • (1) Magazine
  • Cable Lock
  • Owner's Manual

Product Features

  • Flat top Picatinny upper receiver and same-plane Picatinny gas block for easy attachment of magnified optic, red dot or open sights.
  • 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.
  • 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.
  • Patent pending Barrel Nut and Delta Ring are designed for one person handguard removal and installation. The design accepts most standard carbine length handguards. The barrel nut uses a standard wrench and can be swapped with a Mil-Spec barrel nut if desired.
  • Milled gas block with integral Picatinny rail is located at a carbine-length (M4) position for improved balance and handling.
  • 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 operational 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.
  • 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.
  • Single-stage trigger provides durable and reliable fire control. The enlarged trigger guard is designed to allow gloved shooting.
  • Handguards are made from heat-resistant glass-filled nylon for shooting comfort and durability.
  • Also includes: One, 30-round Magpul® PMAG®.

(5 out of 5) Great AR 556
by from Newark, DE on

This my first AR15 paid $650.00 for it, took it to the range and was very happy with the way it shots, its very accurate and its a very nice looking rifle. Thank you Ruger you made a great rifle..

(5 out of 5) Great Rifle
by from Bloomburg, TX on

I bought my AR-556 some several months ago. It was on sale $ 479.00. I looked at another rifle from a competitor, weighed the brand issue and chose Rugar. My 556 package included a fixed front sight and a rear pop-up site. I found it to be handy, straight shooting and fun to fire. I put a red dot sight on it, easy target acquisition.

(5 out of 5) Ruger 556
by from Old Bridge, NJ on

Nice solid starter AR shot well at the range accurate right out of the box. We shot 3-400 rounds, both Steelcase and Brass... both had no issues! Solid feel and nice crisp trigger... great value and I will purchase more for my sons in the future!

(5 out of 5) I absolutely love this 556...
by from Old Bridge, NJ on

I had taken it you the range to break it in in NJ we cannot have an adjustable stock nor threaded barrel, so after getting the stock to my favorite position, we had the FGL make it NJ Compliant.. This was and amazing buy and is high quality for the price. Thank you!

(1 out of 5) Disappointed
by from Greensboro, NC on

As a first-time semi-automatic rifle purchase, the Rugar AR 556 came in defective. Would not repeat fire. I discarded the box not expecting to have to return the item. I put it in the gunsmith shop, hoping it is a simple fix I am unaware of. But why shouldnt a new semi-automatic rifle, shoot perfectly right out of the box. I hope Im contacted about this, cause it costs to much to have to be repaired straight out of the box. I got a bad one, and need help. Ill probably have alot of trouble to get help from Sportsman,or Rugar on this.

(5 out of 5) Got Exactly What I Wanted!
by from Fayetteville, GA on

I had a hard time locating the rifle I wanted until I ran across Sportsman Outdoor’s website! Even with the delay warning due to covid-19 on their site, they got what they said they had in stock to me when they said they would. Even made it super-easy to track the package. I will definitely be shopping with them again in the future.

(5 out of 5) Ruger purchase
by from Winslow, ME on

I’ve recently purchased a Ruger rifle, very fast shipping to my ffl and customer service is A1. Best prices around also.

(5 out of 5) Well pleased!
by from Grundy, VA on

Very well pleased with the firearm, shoots perfectly. Not only am I satisfied with it, there was also such great customer service that I received from Sportsman's Outdoor Superstore.
 I ordered it on a Sunday night and was shooting it on a Friday evening. Great shipping package and everything. First time I had ever bought anything on-line so what I have received was excellence.
