Product Description

What's in the Box

  • Ruger AR-556 MPR 5.56mm Semi-Auto Rifle
  • (1) Magazine
  • Cable Lock
  • Owner's Manual

The new Ruger AR-556® Multi-Purpose Rifle ("MPR"). This custom-built modern sporting rifle features an 18" nitrided alloy barrel with rifle-length gas system, Ruger's 15" free-float handguard compatible with M-LOK® accessories, the Ruger® Elite 452™ AR-Trigger and ergonomic Magpul® furniture. The perfect rifle for a variety of uses, the AR-556 MPR is capable and versatile.

Ruger's talented team of engineers worked carefully to develop the ideal custom package for the AR-556 platform that does it all, right out of the box. From plinking to competition shooting, the MPR is the perfect rifle for just about anything.

The MPR's cold-hammer forged 18" alloy barrel with 5R rifling is salt bath nitrided for corrosion resistance and durability. The barrel is contoured to minimize weight without sacrificing rigidity, leaving a 0.75" journal for the low-profile gas block. The soft-shooting, rifle-length gas system paired with a Ruger® muzzle brake provides smoother operation and softens recoil to keep every shot on target.

Ruger's 15" free-float handguard is light, stiff and versatile, with Magpul M-LOK accessory attachment slots along the 3:00, 6:00 and 9:00 positions. Additional slots on the angled surfaces near the muzzle are perfect for mounting a light, laser or QD sling cup. Compared to a typical quad-rail forend, the 1.50" diameter handguard makes the MPR's forend slim and controllable. M-LOK-compatible Picatinny rail sections can be easily added. The integral Picatinny rail at the 12:00 position is tightly controlled to the most current STANAG 4649 specification.

The crisp 4.5 pound trigger pull of the Elite 452 two-stage trigger is a great addition to the MPR. The lower receiver is fitted with Magpul's MOE® grip and Mil-Spec MOE SL™ buttstock, making the rifle easy to handle, shoulder and shoot. The Mil-Spec compatible lower and upper receivers are CNC-machined from forgings and hard coat anodized. The MPR comes complete with dust cover, brass deflector and forward assist.

Firearm Features

  • Lower receiver is fitted with Magpul® MOE® grip and MOE SL™ collapsible buttstock on the Mil-Spec buffer tube.
  • Handguard is free-floating for accuracy and the slim, 15" length provides enhanced ergonomics and support.
  • Made from aerospace-grade 7075-T6 aluminum forging, the flattop upper receiver includes a forward assist, dust cover and brass deflector, and is Type III hard coat anodized for maximum durability.
  • Bolt is machined from 9310 alloy steel and is shot peened and pressure (proof) tested to ensure strength, structural integrity and durability.
  • The Ruger® Elite 452™ AR-Trigger is a two-stage trigger that offers a smooth, crisp, 4.5 pound trigger pull. It features a full-strength hammer spring for consistent primer ignition and a lightweight hammer that enables a 30% faster lock time over standard MSR triggers.
  • Rifle-length gas system provides smoother operation and reduces felt recoil.
  • 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.
  • Cold hammer-forged 4140 chrome-moly steel barrel with ultra-precise rifling provides 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 nitrided finish provides corrosion resistance.
  • 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.
  • Ruger® muzzle brake is a radial port design that significantly reduces felt recoil and muzzle movement. The 1/2"-28 threaded barrel allows for standard muzzle accessories to be installed.
  • Also includes: One, 30-round Magpul® PMAG®.

Customer Comments & Questions

Customer Reviews

(5 out of 5) Definitely worth it at this price
by from Augusta, GA on

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.

(5 out of 5) Initial Problem But......
by from Orlando, FL on

My MPR was purchased in November 2017 and had some initial issues. The gun had to be returned to Ruger and they were wonderful in correcting the bolt problem. I have since run close to 3500 rounds with maybe one or two hiccups of no consequence. The MPR shoots so sweet and accurately that several of my friends who have shot it now are ordering for themselves. As mentioned, I had an initial problem that Ruger took care of immediately and perfectly. The Ruger customer service is outstanding if needed. Sure can't say that about many of the manufacturers.

(5 out of 5) Great Rifle for the money exceeds expectations.
by from Wilmer, AL on

I searched and searched for a perfect rifle to suit an entry level AR15. This exceeded my expectations and went beyond. Very smooth shooter, light and accurate. Ruger really took their time with this one. I’m so happy with it, I’m thinking of getting the .450 bushmaster version. Would highly recommend to anyone contemplating on getting this rifle. All of the bad reviews and videos on Facebook, those issues have been resolved and shouldn’t be looked down upon, this is a great buy. Great job Ruger, another well American made rifle.

(5 out of 5) Cant ask for more
by from Hannibal, MO on

500 rounds through mine so far, of all varieties. No hiccups. Shoots soft with the rifle length gas system. Took my comp off as it is unnecessary and to cut down on noise. Trigger is phenomenal for the price. This gun is ready to go for whatever you need it for, right from the box. I added a 1x8 Burris and a Geissele 3 gun trigger and it rains hell on steel.

(5 out of 5) Very nice mid range AR
by from Crystal Springs, MS on

The Ruger MPR exceeded my expectations. On delivery I field stripped and check lubrication. All was good. Then ran 100 rounds through it with absolutely no issues at all. The trigger pull is so nice for a mid range rifle. This is a fun gun to shoot. I am a happy camper

(5 out of 5) Best AR for the money
by from Miramar, FL on

I own several AR15 Including a Wilson and other Custom built all up 2 to 2500k. This ruger is amazing.  I bought it because of the price, never expected to be such a nice weapon. Added a set of JP trigger light springs pull now under 3 lbs. No it is not an Elftmann or Hiperfire,  but is top notch.  Very soft shooting 500 plus rounds not one problem Ruger great job

(5 out of 5) Great rifle for the price ....
by from Midlothian, VA on

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.

(5 out of 5) Can't be beat for $600
by from Salt Lake City, UT on

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.

(5 out of 5) Great Rifle
by from yorkville, IL on

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.

(5 out of 5) Buy with confidence!!
by from Austin, TX on

I have been researching a mid level to budget level rifle in the AR platform for a little more than a year, and had watched many review videos giving good and bad reviews. I finally decided to stick with my initial selection and purchase the Ruger MPR.

When taking it out the first time I was a little worried about some of the various bad review/issues I had heard about. Absolutely no issues with this thing!! I’ve spent around 400rounds through it, of various grain and brands, both 223 and 556. This thing is so incredibly accurate! I took out 4 hogs at about 150yds, and have practiced plinking at a target that was around 320yds away. All of this done with a red dot sight. I can’t wait to get a scope for it, but cannot stop saying enough good things about this rifle.

Buy with confidence!! Also, this was my first online gun buy, and SOSS made things very easy and super quick! I’ll definitely purchase here again.

(5 out of 5) PERFECT RIFLE
by from Philly, PA on

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.

(5 out of 5) Right out of the box put 200 rounds through it after cleaning & lubing
by from Longview, WA on

Got the rifle to my city fast as I payed for next day shipping. My FFL took awhile to process it as I went through a business mistake; they can take as long as they want to process it so I wasted $30 for shipping. Not Sportsman’s fault though. Or FedEx. I cleaned and lubed my rifle up and took it to the mountain to put roughly 200 rounds through it over 3-5 hours. I had 3 types of ammo to try in case this was gonna be a picky gun. Winchester 5.56, Remington UMC .223, and Hornady Black 5.56. She ate all of them up no problem. People claimed feeding issues but fail to realize the AR15 platform, no matter which one you get, needs to be properly lubed and you should have an amazing rifle. If not still then it should be sent back. Because the AR556 MPR is the most bang per dollar rifle on the market in my opinion. It performed amazing and is exactly what I expected from Ruger 10/10 job on the build.

(5 out of 5) Love the gun
by from Wauseon, OH on

I ordered on a Saturday and received on a Thursday. There was an issue with my order and had the best customer service there is. The gun is amazing, shoots good and looks cool af.

(1 out of 5) Buy with caution
by from Houston, TX on

Bought mine back in Sep 2017 with working offshore. I didn't shoot it until Feb 2018. A friend of mine bought the same gun and we went to the range together. FTF FTE in both guns and a FTE that still tried to cycle the next round pushing that rounds bullet into the casing and spilling powder all over the inside of the gun. At this point I was not too keen on trying my luck any longer. So with under 2 mags painfully through it I will be sending it back. I am comfortable tinkering with internals, but this issue is not something I want to spend multiple trips to a range to correct. The tolerances in the bolt or where the bolt locks into the barrel is off. I cannot even put a round in and pull the charging handle to eject and cycle another. This requires an extreme amount of force, slamming the rifle on a hard surface while pulling the CH.

I have another Ruger AR that I have owned for years and put 1000s of rounds through with none of these issues. Hopefully Ruger will hold up to their great customer service rep. The gun itself is a hell of a deal for what you get, but in my case QC must have had a day off. Federal and Freedomunitions FMJ 55gr ammo used. Same ammo used in my other ARs with no issues.

(5 out of 5) Best bang for the buck
by from Houston, TX on

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.

(5 out of 5) Some issues, but a great rifle over all
by from Longmont, CO on

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.

(5 out of 5) Unbelievable value.
by from ALBANY, OR on

With an estimated 400 rounds through this rifle I am very impressed. It has had zero malfunctions with at least 8 different ammo types. The recoil impulse is very smooth even with the muzzle brake removed. I am so impressed by the rifle length gas system I am switching all my AR15s to it. I estimate it to be a 1.5 to 1 MOA rifle with factor ammo. The tigger is nice. It shoots better than my POF Renegade costing around 1200 dollars. This is an incredible value.

(3 out of 5) There’s a reason it’s $650
by from Laguna Vista, TX on

This rifle really does come with some nice features. The trigger is first class and the magpul furniture it comes with is high quality and saves you a few bucks. The muzzle break is genius and makes it to where with rifle hardly has any recoil at all. Functionality wise tho, that’s where this rifle starts to show why it’s priced the way it is. The mag almost never catches the bolt when it’s empty. For some reason that just wasn’t a thing on my rifle and I was using magpul mags. Double fed all the time, probably about once every 40 rounds. The bolt itself was started to deteriorate after just less than 200 rounds. ALL I SHOT WAS FEDERAL .223 BRASS. As soon as you realize your enternals are falling apart on you that’s when it’s time to jump ship. Sold it for $50 more than what I payed for it and got a Springfield Saint freefloat. The gun shoots actually really well when something isn’t going wrong but for $600 reliability and longevity woes should be a thing of the past.

(4 out of 5) Good Value Rifle
by from Houston, Texas on

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.

(5 out of 5) Top notch
by from San Antonio, United States on

I have owned several ARs. The MPR is without a doubt the finest AR I have ever owned. Everything is just as advertised. Great trigger pull, smooth as silk felt recoil, spot on accurate. No reason to buy an entry level AR for between $500 and $600 when you can have this gun for $650 from SOSS. Get it, you wont be sorry.

(5 out of 5) Love the Ruger MPR but needed a few adjustments
by from Bossier City, LA on

I absolutely love this rifle. First 200 rounds shot with zero malfunctions. Shot fiochi 55gr .223, and some federal 5.56 and it ate the ammo up. There are a few things that I found initially that I wasn't too happy with. The handguard wasn't installed evenly, it was slightly off to one side. No big deal, simply loosened set screws and moved it to center. I was worried it would walk off center, after shooting 200 rounds it maintained center. The gas tube roll pin was installed sloppily. It looked like someone was in a hurry and didn't push the pin all the way through, and mushroomed the pin so it wouldn't go in any further. This did not affect the function of the rifle, and I may replace the roll pin at some point.

The bolt and carrier were extremely tight when I first got the rifle, so tight that I had to use the fwd assist to get the bolt to seat. This was resolved with some LCP around the gas rings. The tolerance between the bolt gas rings and carrier is extremely tight. After running the bolt open and closed 100 times and lubing the bolt everything smoothed out nicely. I highly suggest you do this before taking it out to shoot for the first time, it will ensure you have a malfunction free shooting experience.

The trigger is excellent, the 2 stage trigger compliments the enhanced accuracy of the 18 inch barrel. I may actually purchase an other Ruger 2 stage trigger for another AR build I am planning.

Overall a good rifle, just needed a few adjustments which are not a big deal for a rifle which offers such a great value.

(5 out of 5) amazing looking rifle!!!
by from Indianapolis, Indiana on

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!!!

(5 out of 5) Best Value on the Market
by from Herriman, Utah on

For what you get with this rifle package, you simply cannot buy or build anything even close to this quality, at this price point. I honestly don't know how Ruger is selling these things for only $100 or so more than their basic 556. Cold hammer forged barrel with melonite, Magpul furniture, free float rail, muzzle break, and a trigger that is 100 better than a mil spec. It would cost over $1000 for me to put this rifle together, but they are selling for around $600. Rifle shoots great. I have had on issues with feeding, or the bolt failing to lock back, like some others have mentioned. This is a very tight rifle quite impressive actually, so if things are not oiled regularly, I would expect some of the issues others have mentioned. If you are on the fence about buying this rifle, just do it, you wont regret it.

(5 out of 5) Great service
by from Doral, FL on

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

(3 out of 5) It's ok, not great
by from Fort Worth, Texas on

Received mine a few weeks back and have finally put some rounds down range with it. Here are the pros and cons.

Pros: Almost no recoil. It literally felt like I was shooting a loud .22 LR. Only when I started to squeeze of rounds fast did I start to jump around a bit. But easy to stay on the target. 120 brass rounds, cheap Monarch, not one jam. Free float hand guard has no wobble. And all the Magpul furniture was comfortable to work with. Sad it doesn't already come with sites, but for 599 no tax, no shipping, I wasn't going to complain. Basically this was a joy to shoot.

Cons: OMFG, that front take down pin was horrible. I have served firing the M16 and M4, never once was a take down pin so difficult. I literally had to have a punch and tack hammer to get it out, and to put it back in, the tack hammer again. And I oiled the hell out of that pin and hole. The back pin was easy, pushed with my thumb and was able to pull it out no prob. Even after a few taps and replace it is still not budging by my thumb only. Still having to use a punch and tack hammer. Remember how I said I only fired 120 rounds Well the bolt cam pin was already gouged pretty good. And the whole carrier group felt tight. Even after cleaning and reapplying oil. Will have to keep an eye on it, but already looking for a carrier group replacement.

All in all, fun gun to shoot, but I will be contacting Ruger with my concerns on the take down pin and carrier group.

What an accurate and smooth shooter! Honestly impressed. Ruger made a very nice rifle at a very reasonable price! Scoop one up before they realize what they have here and jack the price up! Thanks SOSS for the quick one week transaction and great price! I will definitely do business through you guys and girls again!

(5 out of 5) Great rifle.
by from El Paso, TX on

I would definitely recommend this MPR to anyone. I have had it for about a month. Very accurate rifle so accurate I have been taking out rabbits while they run. My only problem is getting the bolt to lock back after the magazine runs out of ammo. Awesome rifle though. I get groupings less than a quarter at 100 yards.

(5 out of 5) Nice Gun
by from Harrisburg, PA on

I am by no means a great shot but this gun works for me. I spent about 30 shells sighting in my 5 MOA Bushnell red dot and the aftermarket iron sights. At that point I was able to hit any 6 plate up to 110 yds on demand speed fire while on the bench. My buddy said now stand up and free hand it. 4 shots, 4 seconds, hit 6 plate at 110 yds completely free hand. 2 group at 110 yds with the iron sights on bench. I'm satisfied.

(5 out of 5) MPR 5.56 recoils like a 22 cal
by from Hollywood, FL on

Thank you Sportsman for the fast turn around time on the shipping came in a few a days early. Phone good customer service. Simply put, Best 5.56 on the market right now for the money. Shoots 5.56 and 223s. kicks like a high powered 22 cal. My friends Daniel Defense kicks like an old M16 hard. Ya I know, barrel differences..blah blah blah. bolt is easily upgrade-able to a F.A. bolt mil spec. Distance is outstanding with a scope of course. I don't think, I will need to put 10,000 rounds through it. It's a S.H.T.F. Rifle for me. I added some goodies of course green laser, 9x32 scope, red dot, and of course good old sights and got 10 Sec adman mags. Too good to not take on price value and a 10 clip rifle bag. And still came way under my friends cost just on his DD.

I own several Rugers so when this rifle was released, I had to have one. I have a Ruger SR556 and an SR762, and I love both of them, but I paid well over a thousand dollars for each of them. The MPR was less than half of those but still impressed me very much. I really like the 452 trigger and with the magpul furniture and rail already on this rifle I cant ask for more. I've ran about 300 rounds through my MPR with no issues. I can't say enough good things about this rifle and the amazing value it is. If you are in the market I recommend the Ruger MPR.

(5 out of 5) GREAT SERVICE
by from Mesquite, Texas on

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.

(2 out of 5) Reliability woes
by from New Baden, IL on

I really like the features on the MPR. I added an ambi safety, ambi charging handle, flip up irons and a Vortex red dot. The gun works great with brass ammo. But very poorly with the three different steel case loads I tried. Even after a full cleaning, I get a failure to feed about every 10 rounds with steel. Sometimes it wont pick up the fresh round from the mag, sometimes it hangs up on the feed ramps. Sometimes the bolt won't lock back on the last round. I used the same loads and mags on the same day in my 2010-era Rock River A4 with 100% reliability. My MPR will go back to Ruger for a look after Xmas. My only reason for waiting is wanting nothing to do with UPS this time of year! If Ruger can get it working right with steel ammo, I'll likely rate the MPR in the 8 or 9 range on performance... I just don't enjoy sending it back for a do over.

(5 out of 5) Best overall value in the market!
by from Spanish Fork, Utah on

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.

(5 out of 5) Ruger MPR
by from Scott Depot, WV on

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.

(5 out of 5) What a Deal
by from Central, Texas on

You're getting a lot of gun for the money with the Ruger AR556 MPR. I've only put 40 rounds through it, but it functioned flawlessly and is very accurate. The OEM BCG worked just fine, but I replaced it with a PSA Premium BCG just because I don't like the unshrouded carrier that comes with the rifle.

(4 out of 5) Almost Perfect
by from Memphis, MI on

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.

(4 out of 5) Great rifle one mistake...
by from Omaha, NE on

SO, I got my new Ruger AR 556 MPR from Sportsman's here, and it is a great deal. I took her to the range yesterday after throwing on some flip up sights and proceeded to fire away. After 2 mags I noticed something...The hand guard had some play to it...started to twist. I took it to the owner of the range to ask his opinion also my FFL, and looks at it and states the barrel nut is not tight, only thing really keeping the barrel on is the gas tube at that point. COME ON RUGER. So, I faced the whole send it back pain in the butt, or just have him look at it further and adjust as needed. Could do it myself, but with it being new I was just pissed and figured I'd let him do it. I'm sure it will end up being minor...And everything else about the rifle is great.

(5 out of 5) Killer deal for the money!
by from Lenoir, NC on

If you buy the elite Ruger trigger by itself, it's like $150 and the Magpul stock is around $50, I believe. In addition, you get the Magpul grip and the freefloat handguard which probably has a combined total of $100-$120. The upgrades to the Ruger AR-556 are very impressive. I am about to order mine right now. I already know Sportsman Outdoor Superstores service will be good so I'm giving it 5 stars all the way around. Job well done Ruger!

(4 out of 5) Nice gun with one problem.
by from Sugar Grove, IL on

I pre-ordered this rifle and the price was very good. I mounted a Nikon 223 4x12 scope with Nikon P223 mounts on this Ruger. I could not get the bolt for the forward scope mount through the slot on the handguard rail because the notch was machined too high at the bottom. I slid both mounts back on the rail of the receiver and mounted the scope there. I ran 200 rounds of Russian 556 through the gun without a malfunction. Very tight group in the center of the bulls-eye at 100 yds. Overall I am very happy with the rifle and would have given a 5 rating instead of a 4 if I had not had the problem with the forward rail. I own 2 Colt 6920s and 2 S&W M&P ARs. I recommend this Ruger AR556 MPR.

(5 out of 5) Simply Outstanding
by from North Texas, TX on

Free float rail, awesome trigger, rifle length gas system, very light, nice finish. You are getting a crazy amount of AR for the money

(5 out of 5) Amazing
by from san antonio, TX on

This isn't my first rodeo. I have owned several ARs. But, none as sweet a shooter as this AR. The radial port compensator and the increased gas tube length make a significant difference in perceived recoil. I put about 200 rds down range on my first trip to the range. Bushnell AR scope mounted, 1st shot 6 in low at 50 yds. Dialed in about 45 clicks 2nd shot about 1/2 off dead center. All the remaining shots within 1 moa of dead center. Real nice trigger, just a very solid AR. If you are looking for your first AR or simply a upgrade, get this gun. You will never look back on your decision.

(5 out of 5) Great price and great AR
by from Albuquerque, NM on

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.

by from Saint Charles, MO on

This rifle is almost too good to believe, but its not. I ordered this rifle on the 18th of September and it arrived at my FFL on the 28th. I broke it down and it was very well oiled. The barrel needed a bore snake through it. I bought some cheap pop up sights on Amazon, they are OK.I picked it up and took it to the range same day. I bought 3 different types of ammo: Golden Bear, Tula and IMI. They all fed great with Zero issues over the course of 250 rounds through PMAGS and GI mags, I only shot 20 rounds of Tula because I don't care for it. It is a soft shooter and the trigger is great. Buy it.
