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®.

(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.

(5 out of 5) Everything you expect
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.
