  • (1) Magazine
  • Cable Lock
  • Owner's Manual

Affordable, American-Made modern sporting rifle with the rugged reliability that you have come to expect from Ruger. 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.

Firearm Features

  • 11" aluminum handguard is free-floated for accuracy and features Magpul® M-LOK® accessory attachment slots along the 3:00, 6:00 and 9:00 positions with additional slots on the angled faces near the muzzle.
  • Flat top upper receiver features a Picatinny rail for easy attachment of magnified optic, red dot or open sights.
  • 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.
  • 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 heavy 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.

(5 out of 5) Everything's perfect!
by from La Vergne, TN on

I ordered this the Saturday before Christmas. Arrived Christmas Eve, 3 days after placing the order. Unfathomable all things considered. Oh and my FFL closed at 3 p.m.

 As for the gun itself, it's perfect. I've wanted a modern sporting rifle awhile now. Arrived well oiled, and chewed through the 120 rds of 55 gr .556 ammo I ran through it with absolutely no problems. Y'all are the best!

(5 out of 5) Excellent fit and finish- great price
by from FOREST, VA on

A typical Ruger product, excellent firearm priced far below comparable arms. A shooter that gobbles up any ammo run thru it. My rifle was shipped quickly at a fair price. Sportsman's Outdoor Superstore is #1 with me.

(5 out of 5) Worth the money!
by from Deatsville, AL on

Well made, accurate, reliable and well priced entry level carbine. All the bells and whistles that I wanted in a backup rifle without the huge price tag. Going behind the seat in my Jeep for light ranch work. I couldn't be more pleased.

(5 out of 5) Much more rifle than I expected for the price!
by from Roanoke, VA on

First, let me say I'm not a gun snob. But I do tend to purchase as close to top of the line models as I can, taking into account great deals. I initially bought this little rifle to be left to my grandson, who just turned 1. In 17 years, he might appreciate this old timey rifle.
 Out of the box I was fairly impressed...an AR platform with the Ruger name, USA made for under $470. After closer inspection, this rifle started impressing me more and more. The fit and quality was way above a sub $470 firearm. So I decided to run a few rounds thru it. After slapping on a Nikon 3x9 and a quick bore sighing, I was easily shooting .75 MOA groups of 3 rounds at 100 yards. It does string slightly high and left as the barrel heats up. So I let it cool down and slowly ran some Hornady .223 Superformance Match 75g BTHP rounds thru it. 3 of the 5 shot group were touching. A true MOA rifle. Impressive! Tomorrow I'm going to put a better scope on it and using the same ammo, I'm gonna leg it out to 300 - 500 yards. We'll see how well it does since the weather conditions should be perfect.
 All in all, for a budget Ruger AR this thing is amazing. If you're looking to get into the AR platform, or just wanting another one for whatever reason you can never have enough firearms, this rifle is a steal at $469.99 and free shipping.

by from Naperville, IL on

The website stated that shipping is delayed. I ordered this AR on Friday 10/11 and it was delivered to my FFL dealer on 10/16. Got exactly what I ordered and I’m very happy with the experience.
