Ruger AR-556 MPR 5.56mm Semi-Automatic Multi-Purpose Rifle

Only use the magazine it came with and Daniel Defense mags, or you’ll jam up every time. Scary ****.

I bought this rifle several years ago, and it is the least accurate rifle I own. It produces 5-7 inch groups at 100 yards when bench-rested. It sits unused in the safe because it's no fun to shoot. While it looks good and functions fine, the accuracy is dismal.

One of the absolute best guns I own, shoots great. I recommend it to friends

This is an excellent rifle. The trigger is one of the best out of the box Ars on the market that I am aware of. This rifle shoots great, have used on hogs and otters. Ruger is a great company for economical and quality firearms. The service with SOS has been remarkable!

Had a problem with it feeding changed the bolt carrier group to nickel boron which I was going to do anyway doesnt like steel cased ammo no big deal overall pretty accurate.

WILL BE BUYING FROM YOU GUYS AGAIN ! I LOVE MY MPR 10/10

As a left handed shooter, I was concerned about getting hit in the face with hot brass, but in all the youtube videos I found the brass is deflected to the right and forward. Ive run about 100 rounds through it now, and I havent been hit yet! This is my first AR`;` I like it.

Seriously a great shooting rifle, 2500 rounds since I got ,no hiccups, my son got the same one ,recommend highly.

I’ve had this weapon for about a year and a half now. I’ve added a few things to it. It’s never let me down. I put well over 2000 rounds through it without any malfunctions whatsoever. I would definitely buy another one and I would highly recommend this to anyone. I’m glad I got it when I did when it was $569.

Fast delivery even in the mist of what going crazy in the world. Took 5 days total, picked it up from my FFL and went to work placed 200 rounds at first sight through this bad boy and it didn’t disappoint. If I have to order a gun it will always be from Sportsman’s Outdoor they have won me over......

Awesome gun that has not failed me yet! No issues so far and very accurate with little recoil compared to others that I have shot. Got a nice scope and a bi-pod and it works and feels great. Definitely recommend this gun to anyone that is in the market for one, and the price is worth it.

What can I say the AR does all the talking. I have put 500 rounds through it so far and it begs for more. I didnt clean it from the factory, I know what a idiot, yet with that said the gun didnt have any hang up what so ever, that was the first 100 rounds. I cleaned it and went to place 400 more and I love it.

Loved it so much I bought another for back up! Who knows when you will see another $2000 AR at this price! Thanks SOSS!! Super fast ship to my FFL.

I took it out the range for the first time brand new straight from the box... nothing but problems in feeding and cycling... this is my 4th AR & this one is just complete trash out of the box in my opinion. My first 3 weren’t Ruger. Will be contacting Ruger or soss to see if I can get my $ back or get it repaired. This made my range experience unpleasant... I usually would go through 500 to 1k rounds no problem with my other guns... this gun didn’t even let me shoot 100 rds in 1 hour. Extremely disappointed with this Ruger AR... P.S. I used magpul mags and 55gr hornady 556 rds which cycled with my other ARs with NO PROBLEM... THIS GUN IS THE PROBLEM.

This is my first rifle, I’m 19 years old and I’m a city boy. I wanted something for home defense once I got the go ahead from my mom. I haven’t shot the Ruger yet, but so far so good. I was reading about some problems with the magazines not releasing or other things. Had no issues of that once so ever. I will say 15 days of waiting was probably the most longest day in my life, however Sportsman’s outdoor superstore was really communicative. Shipped it to my FFL and picked it up Saturday. What I can say is that the rifle is beautiful, a sleek look I must say. My next review will be the break in period, hopefully everything holds up.

Arrived on time and took it to the range the next day, shot over 200 rounds with no issues and not a single jam or cycle failure. Would definetly recommend this rifle.

Shoots straight ran 100 rounds through it with no problem works well.

Shot out to 500 yards after 100 break in shoots true no FTF all around a great product

I purchased a few weeks ago and I'm very pleased with this rifle. Comes with a great value of upgrades that I didn't have to do since it came with them. Looks great cause I cant stand the M16 handguards. I love the M lok floating handguards. Accuracy is spot on I can hit inside of a nickle at 25 yards. This is very very accurate rifle.

Perfect in the box took it to the range the next day or so and put about 3 clips 90 rounds in it with not 1 mess up. I even ran steel ammo just to see if it could work with it and it did! 10/10.

This rifle is the best bang for your buck. It has all of the Magpul upgrades you want right out of the box. It is super smooth with very little recoil, similar to a .22. This is a must have for a beginner or a well seasoned marksman.

I've had this rifle for a couple years now. After a short break in, has run 100%. Slapped a 1-6 LPVO on it and its been more than accurate enough for me. Very light recoil, love the Magpul furniture.

Before I buy something, I tend to read a lot of reviews. The same I did before pull the trigger and buy this gun. My experience overall has been amazing. Not a single problem with the gun and seller. I took the gun to the range, not even one malfunction. I switched the CMMG 22LR Conversion Kit, not a problem. It looks like this gun would take whatever you feed it. I even didn't lube for the first time use, and it performed excellent. If people are having problems, it must be lack of proper maintenance/lub or kind of ammo. So far so good and very happy with it.

I have put about 500 rounds through the MPR with absolutely no issues. The trigger is crisp and clean. I have shot several 1in groups from 100 yards. Outstanding rifle.

Just took the Ruger AR556 MPR out to the local range and this gun exceed my expectations! Very accurate gun and very little recoil. Shipping was fast and easy and my buddy kept wanting to shoot some rounds and he has a DPMS Panther.
 My first AR that I have owned. I have pistols and a .22 but this gun will having me at the range every weekend.

I really want to support my local gun shops....but with deals like these, I just cant afford to pay $200 more for this rifle! Amazing deal! The rifle itself is great too. I had been wanting an AR for a while but having never owned one, I wasn't sure what features I wanted other than the free-float barrel / hand guard.

 Well, I love everything about this rifle, it is great looking, fun to shoot, seems pretty accurate haven't really put it to the test yet, and it has been 100% reliable after maybe 500 rounds. I also like the Magpul furniture and the trigger is really good.

 The only thing I think I may change might be the muzzle device. It really is loud and you can't stand anywhere off to the side without a face-full of gas and feeling the blast in your chest. I think something that would direct all of that forward would help.... maybe a Kaw Valley Precision linear compensator ....I know that this muzzle device was developed to help reduce recoil. I don't know if it is due to that or not, but the rifle has a very soft recoil and is a really sweet shooter.

Seriously folks, with the cold hammered forged 18 nitrided alloy barrel, a 15 free float hand guard rail, the upgraded Ruger Elite trigger, as well as a rifle length gas system as opposed to the carbine length as well as coming with Magpul furniture... What's not to like at this price point... At the moment all I've done to this rifle was to go ahead in properly cleaning and lubing it out of the box.
 Learning from past experience as well as reading through some of the reviews, is spring for the all steel constructed Magpul Industries MBUS Pro Flip up sights along with the Magpul Industries M-LOK Hand Stop kit.  This past weekend I took my MPR to relief rifle range and fed it 90 rounds of Federal Brass case .233. and it ran flawlessly.

I bought this rifle as part of Black Friday, and I am overall extremely happy with it. Make no mistake, this rifle is not really a high speed low drag rifle for room clearing, but is more geared towards being a versatile long-ish range rifle for sport shooting and hunting. But for that purpose, it is AWESOME.

 I added a Vortex 1-6 Strike Eagle scope to it, and immediately started punching 2 inch groups at 150 yards with cheap surplus ammo. The MLOCK hand guard is a good touch too, since I can add accessories like a bipod or whatever, super easily if I choose to. The full length gas system is also a plus, as it makes it shoot very softly. Also, the trigger, out of the box, is super clean and crisp, much better than I expected at this price point. In fact, at this moment I have no intention at all to replace it, which is saying something for someone like me.

 As of now, my only complaint is that out of the box, my rifle was poorly lubricated, so I had some pretty serious issues with failure to feed/eject for my first 30 rounds or so, but some cleaning and a generous amount of lubricant has fixed that issue. I can't really say much about long-term reliability, as I only have 300 rounds through it right now, but so far it has been spot-on. Overall very pleased with this rifle!

I enjoy the performance engineered of the MPR

I bought this as my first 5.56. I don’t care about being flashy, and I don’t mind some of the parts being “lower end.” All I want is a gun that runs without fail and shoots true. This is what I wanted and more - really nice gun. It’s a heck of a bargain for a quality 5.56. I know people who have dropped well over $2000 on a custom 5.56 and shoot less than I do - I’m not a professional, not law enforcement, not military though I do greatly respect each and every one who is and if things had gone slightly differently for me I probably would be part of that world, but I’m not.
 Maybe in some cases you’d want something more, I suppose it depends on your purpose. For me, this is perfect. Hope anyone who is on the fence sees this review and recognizes it for what it is - regular guy, regular gun, good quality, shoots true, doesn’t fail or hasn’t yet, another happy buy from Ruger.

The rifle arrived at my FFL earlier than expected. FFL had to do compliance work and $175 later, I was shooting this awesome rifle.

 Accuracy: I'm using Vortex Strikefire II red dot bore sighted @ home. The first group I shot was 1/4 apart @ 25 yards about 1/2 @ 40 yds. I've shot about 400 rds now with no issue. Trigger Pull: the trigger is quite effortless. I don't know how many lbs but it is much easier to pull than my Glock 41 measured @ 5.3 lbs, so this might be around 4 lbs guesstimate. Recoil: what recoil! I was shooting 62 grain 556 and I hardly felt recoil. Must be the muzzle brake because it has about 1/8 pad on the stock you don't need pads on this one.

 Overall, I'm very happy with this rifle. And the only thing I might want to do in the future is change to 16 1:8 twist barrel, but I don't know. I'm so happy with the performance, I might scrap that idea!

I bought this rifle about a year ago and put it through the paces before deciding to write a review. I put about 1,000 rounds through it and have not had any issues with the gun. Rugers Elite 2 stage trigger is excellent out of the box and way, way better than standard mil-spec triggers you get at this price point. That trigger alone is worth $100 over the competition from the likes of Smith & Wesson and Springfield, etc.

 Also, the Magpul furniture and Rugers muzzle break is a definite improvement over mil-spec A2 flash hider and grip as I really dislike the finger groove. BCG had no problems at all but I upgraded it to FailZero Nickel Boron BCG and replaced the original charging handle with Strike Industries Latchless Charging Handle. Swapped out the MOE SL buttstock with Magpuls CTR buttstock because I think it looks better. Mounted QD attachment as well as pic rail on the side of the handguard for mounting a flashlight. Also added offset iron sights and Leupold 3-9x40 scope for the optics.

 All in all, I spent $600 for the rifle and about $650 in additions and upgrades to make the rifle really function optimally to my liking. The performance of the barrel was excellent enough that I did not feel the need to upgrade it. My only con with this rifle is the 18 inch barrel when it comes to overall handling. It feels a tad more cumbersome handling it than your typical 16 in. barrel AR rifle. For short range, close quarter type of shooting, I would rather go with 16 inch barrel or better yet, an AR pistol. Otherwise, the Ruger 556 is an excellent choice in this very competitive AR price segment.

Wow, I have a Colt LE6940SOCOM cost me $1600 and this Ruger is on par and is a pleasure to shoot. The trigger is as good as the 2 stage Geiselle I put in the Colt to replace the gritty junk common on AR15s. The grip, foregrip and rock solid magpul stock are great and the muzzle brake is excellent.

  Some blow back but not an issue. Used the same hand loads I use in the 1.7 twist Colt and after 3 shots to zero, shot sub 1 inch moa groups at 50 and 100 yards using a Vortex Strike Eagle 1x6. Using range marks hit 3 inch at 300yds. Recoil and rifle are light compared to the Colt and the m-lock foregrip is slim and not plastic. Honestly, other than the scope and foregrip I will add a bipod and being a lefty an ambidextrous safety, that's it. Have no doubt, that working a little with loads, this will do .5 groups at 100 with 55gr vmax

Just got this gun a couple days ago. Today is the first shooting, every 3 shots or 2 shots, the charge handle and bolt carrier got stuck. It started failing to feed, and the magazine would not stay engaged inside sometimes. I broke down the gun at home and found there is a small piece of a part on the bolt that is a little more raised than normal so the bolt kept scratching the bolt carrier inside. That made the bolt very hard to go in and out. Will call Ruger and figure it out.

This is my first AR15 rifle and I think it’s a great one! It shipped really fast and was in my hands within 6 business days. They swapped out the 30 round mag for a 10 round mag since I am in CO, which was awesome. There were no issues after testing first 150, rounds everything worked smoothly. Looking forward to getting some more rounds through this rifle, can’t wait for the next range day!

Product was shipped quickly and price was very reasonable. I had compared at other places and this was the best bargain I could find. I called my local gun dealer and he priced around and told me his cost was around $75 more with no markup .

Another fine firearm from Ruger. I love it and my other Ruger firearms. I thank Sportsman’s Outdoor Superstore for selling this firearm for a great price and a Ruger for making it, I am 100% satisfied with this purchase and received it in excellent shape and a timely manner.

I have had a number of CARs during my career including a Colt. The Ruger MPR is by far the finest rifle bar none, especially for the price... $579.

This shop has the lowest price for this rifle that I’ve seen - other “major” retailers wouldn’t even come close when asked to price match. For this price sub $600 this rifle is hard to beat. The shop sent it out about 3 days after ordering and it took about 5-6 days until it landed at my FFL. My FFL couldn’t believe the deal I got and happened to have a Daniel Defense model in a similar size they just bought used and were asking 2x the price than this one new. Holding both together the DD had a better coating but that’s about it. Rifle is slim and light for its length. The only thing I would point out to people is that it has a nice 18” barrel. So the thing “feels” a bit long compared to a 16” or 14.5” pinned and welded. Especially if you add on a longer muzzle device. I like it but I’m not sure that the extra 2” really pays off in terms of velocity. If they had this in 16” it would be a six star gun. Very smooth recoil with the longer gas system. Like any AR it’s loud as heck and the barrel quickly gets hot. But this gun is hard to beat. And the seller gave good service. Gun was perfect on delivery.

First of all, it has a great 2 stage trigger right out of the box. Best among the sub $1,000 ARs I've tried. Second, 18 in. barrel with rifle-length gas system makes it a really soft shooting gun, with noticeably less recoil compared to run-of-the mill 16 in. ARs. 15 in free floating M-Lok handguard looks sharp and is very functional. Everything else is Mil-Spec or better. While 18 in. barrel is not ideal as a home defense gun but if you don't mind the extra length, it is a great shooting, value-added AR at a very reasonable price. Good job, Ruger.

Got if for $600.00 from here, mostly sub-moa groups at 100 and 200 yards out of the box with a Leupold vx1 3-9x40 and 75 grain American Eagle FMJ, and that from a novice shooter this is my first AR15, and my first time back to the range in many years. The trigger is very nice and the free float 18 barrel is exceptionally accurate for an AR in this price range. I don't see how you can get a better deal honestly. Everywhere else I have looked in gun shops and online, an AR outfitted with an 18 free float barrel, 2 stage trigger, all Magpul furniture, etc...costs ~$1000.00. I have not experienced any issues with magazine catches, feeding or ejecting rounds, too tight of takedown pins, loose fore grips, etc...or any other worries described in some reviews you can find online. I've fired about 80 rounds through it so far. I made sure to clean it well on arrival and run the bolt back and forth with lubrication about 100 times before shooting. I cleaned with a bore snake 3 times on the first trip to the range.

After getting my AR556, I broke it down and cleaned it. It was very heavily lubed. A few days later, I took it to the range to site it in. I fired approximately 150 rounds through it and it was flawless. I own quite a few Rugers, and as usual, this is an Excellent firearm.

Have been shooting this since the day I received it. Except for some cheap ammo that I bought and used that caused FTF, everything is perfect.

Ruger MPR exceeded my expectations. The trigger pull is unbelievably smooth as butter. I ran 200 rounds of American Eagle through it today and no issues at all. I added Ruger front and rear back up sights and Bushnell Red Dot. Awesome combination to complete an outstanding AR rifle. You definitely won't be disappointed with this Ruger MPR.

I experienced some of the start up issues others have written about, but after 200 rds it seems to have settled in nicely. The first 50 rds were rough, couldn't get more than 3 shots off without FTF. Seemed like the bolt was not being pushed far enough reward to cycle properly. I even took the advise of another reviewer and completely tore down the rifle, cleared ever part, lubed every part and put it all back together before firing shot 1. The action is tight and gritty out of the box so I would recommend doing this. Then, as another reviewer said, just shoot it. I keep it clear and well lubed now and haven't had a single malfunction in the last 300 rds. I love it!!! Very accurate, low recoil and the trigger is smooth and predictable. Not a fan of the two stage trigger, but for now every usable. If you are not afraid to tinker with your weapon and don't mind that Ruger is using you for final fitment and quality control, then go ahead and buy one. You won't be disappointed.

For the upgrade on the rifle with the price I paid is a true value. The rifle is nicely made. I had a few TFF and FTE with my first 50 or so rounds, and the bolt fail to lock back on the last round. Maybe it's due to the ammo and magazine combination. I was using Wolf ammo and a Surefeed magazine. I switched to a lancer magazine and a new batch of wolf ammo the gun ran fine. My second outing with the rifle I ran some Hornady ammo in steel casing and it was flawless. I went back to the Wolf ammo and got no issues after that. However, during sighting my red dot scope the hand rail came loose from the upper.

Ruger quality control need to step up here! I re tighten the rail and shot MOA at 50 yards zero. The trigger on this rifle is wonderful, a few of my friends were surprised by the light and crisp of it. I do recommend this rifle for anyone who is looking for an upgrade AR15 without breaking your wallet.

I just received my RUGER AR 15 and it is exactly what I expected . Just a small delay with the gun control debate. I called and I was treated nice by a female rep she assured me it was good to go. There was zero damage from pickup. Everything went great even with small delay. I will definitely buy again thanks sportsman for great service!!!

I ordered my new Ruger MPR on Sunday night, subsequently I called in to change shipping slight charge for expedite and talked to Rachel, she was extremely helpful and changed the shipping immediately and said she would be sure that the rifle shipped that day, yesterday! Well it did and I picked it up from my FFL at 1230 today. thanks Rachel and the SOSS Team!! Jaime

GREAT PRODUCT, GOOD VALUE, EASY TRANSACTION, FAST SHIPPING, THANKS!

I ordered the Ruger AR 556 MPR on Monday morning and picked the rifle up from my FFL on Tuesday. I paid the extra 30 bucks for shipping, but it was well worth it. The rifle is exactly what I expected. I put a Sig Sauer Romeo 5 red dot and some flip up sights and I'm good to go. Great customer service for a first time Sportsman's Outdoor Superstore buyer.

First off, this is not a long range, precision rifle or the ideal CQB weapon or anything really other than an outstanding all-around AR. With the free-float rail, enhanced trigger, Magpul furniture, muzzle brake, and excellent barrel, the MPR has just the right amount of upgrades to make it precise out beyond 500 yards, lightweight, ergonomic and just plain kick a. The rifle-length gas system along with the muzzle brake really reduces recoil and makes follow up shots super quick compared to the standard AR-556 or any other run-of-the-mill budget carbine. I have several hundred rounds through this rifle without a hiccup and haven't had any issues with feeding, ejecting, magazine seating, etc. I have used Magpul Gen 2 and Gen 3 PMAGS and GI steel mags, shot multiple types of ammo, new and reloaded. I use this mostly for sport shooting and jack rabbit hunting and it performs flawlessly. I pre-ordered this rifle for $560 which blew me away. At the current listed price, I still think this is the best overall value in the market.

I have not shot the gun so for now I'm giving 5 stars solely based on my purchase, the extremely fast shipping, the condition of the gun as I received it, the fair cost, and the options on this Ruger AR MPR. I spoke with Rachel and she was very helpful and friendly. I was shocked at how quickly my gun arrived. I online ordered Wednesday morning and picked it up Friday. I was forced to purchase this gun because I had a scope that needed to be installed on something. I haven't owned a Ruger yet that disappointed me and I hope this gun meets my expectations.

For the price you can't come close to what Ruger has here. Some positives. -Magpul stock and grip -MLOK hand free floated rail. Very thin. You can wrap your hand around it for a very nice C clamp hold -Ruger's 552 trigger is way nicer than I expected. I really like it -A rifle length gas system creates a very nice recoil impulse - 18 inch CHF barrel with 5R rifling; you get a little extra velocity out of rounds and it's a very nice barrel overall. The included muzzle break is very nice as well. The bolt and barrel are both magnetically particle inspected together; a very nice quality control step. Some people don't like the wait the gas key is staked but it's just a new way Ruger is doing it with a hydraulic press, however, it's the same staking as the older AR 556 so it works perfectly fine.

Now for the negatives. -I wish Ruger would toss in a pair of irons; it's just a personal gripe of mine. I think all guns should come with them, but the only reason this gun is not 5 stars for me is the bolt. Don't get me wrong, it works perfectly the way it is, however, it is not a full M16 bolt carrier group, so if you wanted to put in a binary trigger, you will run into reliability issues, but that's a very small part of the market. Overall, you can't beat this gun at $600. I got mine for $560. It comes with a very nice barrel and you can't find a rifle length gas system on guns this cheap. It's just a super super smooth shooting gun with very nice premium features for an entry level price.

I purchased in the Pre-Order. For the money, this is a very good AR15. Probably not the best you can buy, but I find that it is a good value for the money. This is my first AR15 platform gun. After adding flip up sights, a red dot, and a few other items I put about 500 rounds through it. The rifle shoots very straight with, what I would call, light to moderate recoil. I have shot a few AR15 rifles other than this one. I had no malfunctions in the 3 range trips it took to fire 500 rounds. All 500 were Wolf 223. I have not run 556 yet. I would recommend this AR15. So far, I haven't found a down side. I would rate my experience and knowledge of the AR platform as advanced beginner. Hope this review helps you decide.
