Description

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.

Great value Review by Semper Gumby

Out of the box it was everything I expected. In the process of moving so only one opportunity to get to the range. Started with 5 round clips for sighting, then ran 3 clips of ten each. Not a single jam or misfire. Accuracy was only limited by my vision! Even rapid fire on last clip was able to keep all rounds in 5in pattern at 50 yds. Just as reliable as those we carried in Iraq, would love to have an ACOG for it, but otherwise very happy with this rifle. (Posted on 11/16/2017)

Great overall... Had to do a little custom work on bolt, extractor pin and slides...
Took weapon completely down and cleaned thoroughly and lubricated... Upon
Firing 1st round it jammed, l cleared jam and proceeded o cf again it jammed. This mag was loaded with 55gr 5.56 x45 NATO fmj . I then tried to run a mag of 55 gr Rem.223, same issue. I got on YouTube and found a gunsmith that in the video walked you through how make any AR take almost any type 5.56 x45 ammo and Rem.223 all brands including steel shell casings.l followed his step by step. The extractor pin was .5000 to long causing the shell to not seat properly in the bolt. Using a dremel I was able to remove the desired amount. Polished the ramps steel case ammo no problem, other than it is so dirty.... But once this minor issue was resolved commenced to run approx six hundred rounds of ammo , mixed it up.... Steel case , some reloads I got from another buddy as well as premium rounds. Approx 400 5.56x45
The other 200 all Rem.223 not a single misfire,jam etc after the custom work.
I really love the feel of this weapon .I love Rugar weapons...have several others.. Its a lot of bang for the buck (Posted on 5/19/2017)

I'm sure the gun is great if you can get it back together. The takedown pin is stuck and I can't even get it back together.

Stupendous Price for above bar assault rifle. Review by Colt S. Wesson

@ $499.99 it's a steal. Not sighted in out of the box. 15 rounds later adjusting front and back sights I was hitting bulleyes.@75 yds to start. They say not to shoot 5.56 rounds through .223's but this AR15 takes 5.56 55 grain brass 5.56 x 45 NATO 55 grain rounds fine. Have fired Fioconni's Remington .223's no problem. Ruger states the chamber takes both calibers but have no confirmed evidence that the barrel can withstand 5.56 caliber hotter rounds. Overall, this is a steal @ $500.00. Wishe'd I would have bought a .308 caliber AR15. Oh well, next rifle I purchase when RK has one I like on sale. (Posted on 3/19/2017)

So i got my rifle while it was at reg price at 659, 2 days later it was on sale for 589. I was kinda upset so i went back and asked if they would honor it... and they did! THANK YOU RK!!! Now as for the rifle, i love it, buuuuut first trip to the range i ran into a problem, i could not empty a mag without the bolt catch locking the bolt back. I could get a few shots off at a time, then it would catch and i would have to hit the bolt release to chamber another round. I noticed the bolt catch was very loose with no spring action. Im a big fan of ruger, but i had a terrible experience with the customer service and ended up not sending my brand new rifle in and decided to figure it out myself. popped the pin to find the spring and plunger compressed in the hole.i got it to come out and put it back together, took it to the range and has ran fine ever since... Also i like the delta ring for the fact its easy to use... but the plastic is just not good. DO NOT OVER TIGHTEN!! (Posted on 3/2/2017)

one bad thing about this rifle...the plastic delta ring, which allows removal of the handguards. this needs to be made out of some other material. if you tighten this a little bit too much, it is virtually impossible to get it loose again. this happened to me, and i had to use pliers to loosen it up. be careful when tightening the delta ring! cheapest part of this rifle which needs to be improved by ruger.

have been looking for a long time for a good AR 556, and stumbled on this one was comparing this to the

with many other ruger products and when this was the gun of week @ RK for 569.00 it was a no brainer, get one when
u can and u wont be dissappointed, Thanks Ruger for a great item and Thanks to RK for stocking it, no wonder they
have trouble keeping it in stock probably the best ar u can buy for the money and built very solid to others i have compared
to at different gun shows and gun shops .

Shot it for the first time yesterday. It was great. Feels solid. Three other people were with me and I do believe they are trying to find one now for them selves. The only problem I need to look into is when I moved into a shady area and the front sight was a little hard to pick up. I am going to shoot a few more times before I do anything on that. I do think I watched a video awhile back and that person had put some white paint on the front sight and it solved his problem. It has filled my need for what I need this gun for, self defense, target shooting. (Posted on 6/27/2016)
Good AR from a great manufacturer Review by Ronnie

I've looked at other AR's but I've never owned one until I bought this one. The S&W AR looked nice but I still can't bring myself to buy their products after what they did in 2000. I have other Ruger products and this AR is as solidly built as my other Rugers are. This is a no frills basics AR but it's a solid one to start customizing on if that's what you want. If that's not what you want then it's still a great rifle that won't let you down. The price may seem high for a basic AR but after all its a Ruger and you'll be happy with it. I got mine at the Winchester Rural King and they were awesome to deal with. (Posted on 5/19/2016)
Very pleased Review by Andrew

I was very pleased with my recent purchase of the Ruger ar-556 at my local Rural King store located in Bonita Springs. After visiting a few local gun shops and not getting the answers that I wanted for locating a Ruger AR system I happen to visit Rural King store in Bonita and noticed they had one on the rack, and after handling it for about 30 seconds I knew I needed it er.... I wanted it.
The Firearms Personnel at the Bonita Springs store are very informative and well-educated in the Firearms business they were able to help me make my decision on purchasing the Ruger AR system online and having it delivered to the store after doing the FFL background check online at the store. By purchasing online I got a brand new unopened box firearm and a flat rate shipping of 9.95 and there is no FFL license fee if the weapon is picked up from a Rural King store.
I bought a hundred rounds of Tul ammo steel case 223 went to Cecil Webb and fired off all of them without a hitch, the platform shoots accurate out of the box and needs nothing more than what you want to put on it 4 looks. The Ruger AR platform can accept any standard AR carbine foregrips for the addition of any accessories that you see fit to use.
I have looked recently on RKGUNS.COM website and have yet to see the sr-556 takedown with 300 AAC Blackout option, this would be my next choice.
Again, a shout out to the gentlemen at the rual King Bonita Springs Florida store as it is a much better place to handle or purchase a new firearm than any of the gun stores that I visited in Fort Myers. (Posted on 5/14/2016)

Does it have a dust cover ? And a forward Assist ?

Really looking into this rifle and I guess the only question I have is to know for certain if the standard front sight is removeable from the barrel. It looks like it would be, but talking with some of the gun guys at rural king today they told me that some of the AR's actually have fixed front sights that the only way to remove them is to switch out the entire barrel to get around it. I'm really hoping that removing the front sight if desired is an option for this rifle, because everything else about it sounds just fine to me. Beautiful looking gun, and I've heard Ruger has some very good warranties and that they stand by their word and take care of their customers. It would be the first Ruger I'd own, but I've held out to buy the right AR the first time around.
