5 of 5 Very nice affordable complete upper February 27, 2021
Reviewer: Brent  
Cant beat the quality for this low of a price. I had a 20% off code in my email for these guys and finally followed through with the submit. Nothing super fancy but its better than your average upper receiver. This is perfect for a low cost build. Spend the extra money on a really nice BCG and you’ll be set. These guys ship super fast. I think I got my upper in the mail about 7 days after order. Just doit, follow through with the order, you wont regret it.

5 of 5 Great for the money February 20, 2021
Reviewer: Chuck H from Marietta, GA United States  
I was surprised by this low cost receiver. You can tell care was taken during assembly, there were no tool marks on the barrel nut, rail fasteners, or forward assist roll pin. The upper is a Brass Aluminum forging enterprises and has the square roll mark on the side and M4 roll mark at the front, above the gas tube hole. The rail is decent quality and has a “made in USA” roll mark, steel barrel nut, and the anodizing matches the receiver perfectly. The gas block is very nice and is aligned perfectly, finish on the barrel is great and headspace checked out. The feed ramps in the receiver match perfectly with the barrel extension. My only small gripes are there was no loctite on the rail fasteners and the alignment of the notch above the mag well groove is pretty far off with multiple lowers (this is just cosmetic and part of the forging, not machining).  If you are on a budget, this upper can’t be beat.

5 of 5 Fit & Finish February 18, 2021
Reviewer: John Derogee from Bronston, KY United States  
Was pleasantly surprised with the quality of this upper and BCG.  Fair price for the market while under liberal government rule. BCG looks to be good quality,  will find out after a few thousand rounds, gas key was staked properly and DEEP which is oh so important.  Thank PMA for timely shipping.  Once i develop load for this barrel, i will do some accuracy testing off bench and update review.  May do video on break in and accuracy testing,  as theres very few out there for PMA.
