Great upper.Review by Don
Quality

Everything fits tightly with my Rainier lower, no issues with upper parts kit or mating the barrel (Larue Stealth) or forearm (SLR Solo Ultralite). Finish is great, my second Rainier upper and will probably use for any future builds as well. (Posted on 8/20/2016)

Great forged upperReview by Fred
Quality

I've purchased and used several of these uppers for different builds. The finish is great on every single one and they fit perfectly. I've mated them up to a number of different lowers I have and they function/fit great! For a reasonably priced and I'd say "better than mil-spec" upper receiver, you can't go wrong with these. I will definitely continue to use these in future builds. (Posted on 5/25/2016)

this item was shipped quick and at my house in no time. the receivers finish is exelent inside and out. the hole where your bcg goes is machined so smooth and Teflon coated, grease your buffer spring and your weapon will cycle like butter. its litteraly so good its showroom quality. p.s peter are you sure you got your sights on strait :) (Posted on 1/2/2016)
Quality basic upperReview by Jeffrey

I bought this offer to match with my James Madison tactical polymer lower. It's nothing fancy, just a quality forged upper for a good budget minded AR build. Fit nice and smooth on my JMT lower. Quality product that I would buy again. (Posted on 1/1/2016)
Picattiny rail does not fit attachmentsReview by Peter
Quality

I bought this upper for a built, and when I installed the scope and the offset sights, I could not make it to stay on snugged and solid. I tried with other uppers that I have and everyone was the way it is supposed to be. I wrote to rainier arms to tell them about the issue, and to my surprise they just asked if I was sure that I was setting my scope and sights correctly... I explained, again, that I had, and that I had tried with other uppers and the fit perfectly. I was expecting an exchange but that did not happen. Very dissapointed since I bought from rainier arms for their previous costumer service and I bought their brand expecting a top quality product. Because of this incident, I will not buy a rainier arms product again, and I cannot recommend their product. I can't say that I will not use their website again, but they will not be my exclusive to go site like they used to be. I will certainly shop around to other sites in my next projects.

Nice but tight fit on RRA lowerReview by SBR
Quality
Value
I ordered this to go on a Rock River Arms lower for a SBR build. The rear lug for the rear pin is too tight and will require fitting. It's a basic forged upper so not much else to say. (Posted on 12/22/2014)
