5 of 5 Quality/prompt April 10, 2020
: Chris Rammage from Arlington, WA United States  
As I have not finished build I can't say anything about functionality but after a detailed inspection the upper I ordered looks to be very good quality. Also it shipped very fast, I had it in about a week. Fantastic for the situation we find ourselves in right now. I will be ordering from them again.

5 of 5 So Far So Good December 13, 2019
: Dean R from YORK, PA United States  
Haven't fired the upper yet, but I did mount it on a lower to cycle some rounds through it using a bolt & charging handle from another 9mm upper.   Seemed to feed and eject fine.
Will probably be a little while till I gather the rest of the parts needed to complete this build.

I was skeptical at first but for the price of a barreled upper I couldn’t be more impressed.. I will be buyin another for my 300blk in the future.
