Ruger's AR-556 MPR's aluminum flat top upper receiver includes a forward assist, dust cover and brass deflector.

The threaded barrel allows for standard muzzle accessories to be installed. Handguard is free-floated for accuracy and the slim 15" length provides enhanced ergonomics. Lower receiver is fitted with Magpul MOE grip and MOE SL collapsible buttstock on a Mil-Spec buffer tube. Includes a 30-round Magpul PMAG magazine.
Firearm Features
- Lower receiver is fitted with Magpul® MOE® grip and MOE SL® collapsible buttstock on a Mil-Spec buffer tube.
- Handguard is free-floated for accuracy and the slim, 15" length provides enhanced ergonomics.
- Bolt is mil-spec 9310 and is machined and shot peened for strength 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 faster lock time for improved accuracy.
- 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.
- Ruger® muzzle brake is a radial port design that significantly reduces felt recoil and muzzle movement. The threaded barrel allows for standard muzzle accessories to be installed.
- 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 reliability, and the matte black nitrided finish provides corrosion resistance.
- Made from aerospace-grade 7075-T6 aluminum forging, the flat top upper receiver includes a forward assist, dust cover and brass deflector.
- Bolt carrier and gas key have chrome-plated inside diameters to provide exceptional resistance to hot gases. The gas key is staked so that it will not loosen after extensive firing.
- Rifle-length gas system provides smoother operation and reduces felt recoil.
- Also includes: one, 30-round Magpul® PMAG® magazine.

Customer Comments & Questions
Customer Reviews
Fitment and finish are not the best quality, tolerances seem slightly off. Really hard to push receiver pins out for disassemblymight be due to the Cerakote. Trigger also had a pretty disappointing rough patch right before break, and would seize until completely pressed or placed back on safe. I've since replace with an Rave RA-140 by Rise Armament. Castle nut came loose after normal use allowing my buffer tube to become misaligned. I've since cranked it down with an armorers wrench and I may stake it or change out the buffer tube assembly all-together. with all that said, if you are familiar with AR-15s and don't mind ironing out the potential issues, this gun has some decent value for its price range. Note: I based my rating on out of box performance, you may get one better assembled than mine. If not, its workable with patience and knowledge of the platform.
This is my second AR556 from Rugar and my first one has been trouble free. This one I wish I could say the same. I have had noting but jamming issues and narrowed it down to a faulty BCG. My biggest issue has been with not having a true barrel. I have had 3 separate scopes on this rifle and have had zero luck zero’n it in. Been to 3 different gun smiths and all came back to issues with barrel and upper assembled. I will be contacting Rugar direct and this rifle has been a lemon from the beginning.
Honestly, at this price point whats not to like starting with the 18 inch barrel and 15 inch free float hand guard, along with the Ruger Elite 452 AR-Trigger which is pretty sweet in offering a smooth & crisp trigger action... no to mention the Magpul furniture and last but not least the Frazzled Brown Cerakote finish is pretty friken bad a$$!! I already owned the Ruger AR-556 MPR in the black anodized finish, but when I saw that this Frazzled Brown Cerakote finish MPR was available I just had to have it and I am not disappointed with either rifle especially with the rifle gas system that they employ as opposed to the carbine gas system.
