Out of Stock



  • Ruger® Rapid Deploy folding rear sight provides windage adjustability and pairs with the A2-style, F-height, elevation-adjustable front sight for a solid, reliable aiming system.

  • Made from 7075-T6 hard-coat anodized aluminum forgings, shot-peened and proof-tested 9310 steel bolt, and 8620 steel bolt carrier. The inside diameter of the carrier and gas key are chrome plated and the key is staked for longevity.

  • Barrel nut and delta ring allow easy, one-person service of the heat-resistant glass-filled nylon handguard. The design accepts most standard carbine-length handguards. The barrel nut uses a standard wrench.

  • 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.

  • Handguards are made from heat-resistant glass-filled nylon for shooting comfort and durability.

  • Single-stage trigger provides durable and reliable fire control. The enlarged trigger guard is designed to allow gloved shooting in cold weather.

  • 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.

  • Equipped with a medium contour, cold hammer-forged alloy barrel with 1:8" twist rifling that provides exceptional accuracy with bullets from 35 to 77 grains. M4 feed ramps and 5.56 NATO chamber allows the use of both 5.56 NATO and .223 Rem. ammunition. The barrel and 1/2"-28 Ruger® flash suppressor have a matte black oxide finish to reduce glare and provide corrosion resistance.

  • Front sight post is elevation adjustable, and a front sight tool is included. The A2-style, F-height front sight allows co-witness with many optics.

  • Ergonomic pistol grip features an extended trigger reach for more precise trigger control.

  • Made from aerospace-grade 7075-T6 aluminum forging, the flat top upper receiver features a forward assist, dust cover and brass deflector.

  • Also includes: one, 30-round Magpul® PMAG® magazine.

My order came loaded with rust and was used. My ppf called and said you need to look at this. They and I agreed that whoever packed this thing needed to be fired. I will have to say gunprime was courteous and quick about picking up the wrong gun and replacing it. That is why I gave them a 4 and not a 2. Now that I have it, I am very happy...Ed

Great online experience

My order was processed and shipped quickly. I received multiple notifications on the shipping status of my order until I was able to pick it up. Very impressive. Thank you.

So far so good with my new Ruger. Only put 20 rounds through it but I can easily see how shooters eat up ammo. Very fun to shoot. Gunprime was awesome, shipped very next day. Will do business with them again.

Ruger AR556

This gun is cheap and amazingly accurate out of the box. Absolutely zero jams and I ran 300 rounds through it the day I got it.

This is a must buy if you are into guns. Without doubt one of my most precious AR i own.

Great shopping.

Purchased this gun as my 1st AR15. I have nothing but good things to say about ordering through gunprime.com. I placed my order on a Friday morning and it cleared my credit card processing period on Monday. Not long after the order cleared I received an Email from gunprime asking me what local FFL dealer I wanted the gun shipped to. I opted to pick the gun up from one of their partners in Birmingham, Al. I picked the gun up on Wednesday with no issues.
This is a very basic AR. I've heard others complain about the trigger being heavy or gritty but mine is smooth and clean. The handgrip is comfortable but I can see it getting slick if your hands get sweaty. Everything else is very tight and clean. This is probably the best bang for your buck you can find.
