(4 out of 5) Not bad for the price if your willing to fix QC issues.
by from Buckeye, AZ on

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.

(1 out of 5) My 2nd Rugar 556, not good
by from Hoffman Estates, IL on

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.

(5 out of 5) Best Value for your Money!!
by from Universal City, TX on

The Ruger MPR has everything that I could possibly ask for on a factory shipped AR. Everything about it is catered towards Accuracy, but the fact that it remains lightweight gives you the ability to make this AR snappy. I opted to use a suite of Sightmark Ultrashot M-Spec combined with a T3 magnifier. Another versatile approach to this multi-faceted firearm.
 The trigger is perfect for just about any situation you would come across. Follow-up shots are easy to manipulate. It's as if the entire AR is in sync with itself. It is good at pretty much everything. And for 600 bucks, you literally cannot beat this. Compare to the Sig M400 Tread, and you would be hard pressed to choose that over this, because of the value you get.
 This particular variant of the MPR will have a much darker finish than these pictures will show you. There is also alot of green accents in the camo. And to me that made it look even better than I expected. If you love your Ruger 556, this firearm improves on it in every way. I wouldn't hesitate to recommend this rifle to anybody looking for a good price point AR.

(5 out of 5) Ruger MPR
by from Bethany, OK on

I bought this rifle last year and have been very happy with it. With rifle length gas system, it has very soft recoil, a nice trigger which you usually don't get on an AR and has been surprisingly accurate. I hand load my ammo and I had no problem getting sub MOA. It really likes the Hornady 60 g. Vmax, loaded with CFE powder.
 I bought it for coyote hunting and it has worked out great for me. I think this rifle is the best buy for money on the market today. My son is considering buying one for himself.

(5 out of 5) Ruger AR-556 MPR Frazzled Brown Cerakote finish is bad a$$!...
by from Hollywood, FL on

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.
