(5 out of 5) Solid Performance
by from Grapevine, TX on

Swapped out the 10.5 for a 7.5, and a quad rail. Got about 1000 rounds through it right now, kinda Regretting that tho since the price of ammo has gone up substantially. Not a single issue. No failure to feed, stove pipes, not a thing. trigger was a little stiff in the beginning, but after around 500 rounds, it got smooth.

(5 out of 5) Fun AR pistol.
by from Ellijay, GA on

After receiving my AR pistol I installed an Eotac sight, really quick to pick up and accurate in fact this pistol is amazingly accurate using the Eotac and a bench rest I was able to place 5 shots in 1.5/1.25in at 100yrds not bad for a 10.5 bbl. Note to any BATF officer reading these reviews, at no time was the brace used as a shoulder stock!!!

(4 out of 5) Well worth it!
by from Atl, GA on

I have a few ARs but like many, you cant just have one. So I thought I would give this Ruger a try. I had read good reviews, and thought it might be worth a run. IT WAS It handles well out of the box, I slapped some iron sights on it, and took it to the range. I can say my first 300 rounds, had better than expected groups considering it was the first time I took it out. I have taken it back a few times now, and I am very use to the trigger on this thing. I know people who rush to upgrade, but I am sticking with it the way it is. The brace is the only thing I didnt like. But I knew that when I bought it. I am not a fan of this type of brace because it just feels cheap. But that was a simple upgrade, and now this is one of my for sure range play toys.

(5 out of 5) Ruger AR -556 pistol
by from laveen, AZ on

I was hesitant to purchase this firearm because you know the cliche you get what you pay for well thats not the case here I feel like I ripped RUGER off , this is a quality firearm straight out the box . I took this pistol to the range and it is deadly accurate with flip up sights I wish I could say its all my skill but ill give credit to the Ruger pistol . Go buy one of these bad boys you will not be disappointed

(4 out of 5) Up front, I dont give anything a top rating ........
by from Auburn, ME on

That said, however, if I did, I would give the Ruger AR 556 pistol top marks thus far. I waited to post this review until I was able to get it on range, sight it, then cycle. So far, I love it. I love the fact that its American made, too. My first Ruger`;` likely, wont be my last. My next one will likely be the full-size AR, then Im curious re: the SR40c. As for shipping and customer service, so far, the unit was shipped in what I felt was more than reasonable time given the current constraints on the system with the virus thing. As for customer service, I haven't had to use them so far. All in all, I'm glad with my purchase and if buying new again, Id look at Sportsmans Outdoor Superstore again as a top consideration. Hope this helps! Peace!

by from Isanti, MN on

My first ar pistol. Got for an awesome sale price. Fit and finish on this pistol is impressive for the price point. Fast shipping/ good buying experience

(5 out of 5) The ar 556 is amazing
by from Tampa, FL on

It did amazing job at the range. I did have a problem during the first test. One of my gas rings in the bolt’s piston had a Malfunction and folded over the bolt and had a Severe jam and had to put it away after the first 60 rounds. Had to buy new gas rings and just recently got them and waiting to go test it again. I'll give an update once i go on the 2nd test.

(5 out of 5) Worth every dollar
by from Shreveport, LA on

3 months owned/ 400 rounds through 0 misfires/ hang ups DEFINITELY RECOMMEND THIS FIREARM

(5 out of 5) Havent Shot It Yet...
by from Aurora, CO on

I ordered the Ruger AR-556 on Thursday 4/16/20 and it arrived at my ffl on Thursday 4/30/20. The firearm shipped complete and in perfect-factory-new condition. I tightened the set screws for the mlok free-floating handguard. Other reviews mentioned they had come loose or were not tight when they got it I attached a seekins precision angled foregrip, 45 degree offset sights, and a red-dot. Cant wait to put some rounds through it!!!

(5 out of 5) Awesome ar pistol even better service
by from Austin, TX on

Ordered last week and it arrived today. That was faster than I anticipated with the backlog of orders right now. Great job Sportsmans Outdoor Superstore you have a customer for life. As for the pistol Fantastic. Just put 200 rounds through it without issue. Accurate and reliable. Very happy customer.

(4 out of 5) Surprised..
by from Norfolk, VA on

I just bought this gun and finally picked it up from my ffl gun shop. I brought the rifle home and bam, first thing there something wrong with the gun. The charging handle won’t unlock. I have to bang from behind to get the charging to come back out and that’s if it does come back out. This is ridiculous! I bought this gun and saw good reviews and now I’m unpleased with this product...

(5 out of 5) Great Gun
by from Detroit, MI on

Great firearm. Shoots anything you put through it. “Stabilizing brace” is perfect. No complaints!

(5 out of 5) Ruger 8570!!
by from Springhill, FL on

Great pistol! I have put 600 rounds through it and the only issues I had was that the gas block was loose. After I tighten it up with lock tight it ran flawlessly, great trigger, overall super happy with what Ruger did. 5 stars all day!

(5 out of 5) Ruger Quality + Excellent Value!
by from Tempe, AZ on

Ruger has created a winner! This is an excellent entry level AR pistol with all of the basic features in an AR pistol. The SB Tactical SBA3 brace is excellent. Placed a Vortex SPARC AR red dot and had it dialed in after a few rounds. Fired several hundred rounds of brass and a couple hundred steel cased rounds without any issues.
 The only item I personally upgraded was the grip. This pistol is an excellent value and defines Ruger quality!

(5 out of 5) Really great pistol
by from Soddy-Daisy, TN on

Purchased this pistol sight unseen and it is really great. I liked it so much that I just purchased 2 more of them. I did do a lot of research on them before I made this purchase and I could not find any negative comments about it at all.
 Ruger has been around a long time and I expect that this pistol will be too. Sportsman's Outdoor Superstore does a wonderful job of shipping it when they say they will and the receiving FFL folks had no problems. Will purchase from them again if I ever have enough money after this 2nd purchase.
