Excellent value
Along with a lowers kit purchased from PSA this went into an Anderson lower, destined to be unadorned light handling woods partner. Delighted with the ease of integrating the pieces; zero build issues & it shoots a tad better than MILSPEC acceptance with my MILSURP ammo, so no issues there either. Super value & the customer service is great.

CMMG 22LR Does Not Work w/this Upper!
I specifically bought this upper for my CMMG 22lr conversion kit and it does not fit all the way in this upper. I have a Colt M4 6920 that the CMMG kit works flawlessly in but is extremely dirty after using the kit. I live in NC and so the free shipping was crazy fast. The fit and finish of the upper is very nice. I bought the PSA Classic lower to go with this and it matched up perfectly. Haven't fired it yet, but I do not expect any issues as my buddies have PSA rifles that fire just fine. I will go to PSA again for my next build.

Works Great
I don't really understand what you can do wrong with an upper but this one is amazing. Love the MBUS and the BCG. Nothing is loose or wiggly I only have about 60 rounds through it and it performed amazing, there were no malfunctions even when I di a mag dump. So overall it's amazing.

Premium in my book
It looks and feel premium, no blemishes and everything fit and feels great, functions flawless so far, about 600rnds down range. Mounted on a Spikes lower and everything is great so far.

Excellent product
Excellent product bought two of these. I matched them with Anderson lowers for the price you can't get any better. Shot 200 hundred rounds of assorted ammo through both. They functioned perfect with anything I fed them .Shipping was fast ! Once processed. which was less than the ten days they advertise before ordering.
