Very nice complete upper August 19, 2022 : Nathan from CA United States   I have to say I was not expecting how fast the shipping was. It came right on time and the build quality is excellent! I would say this upper is a perfect weight that balances out nicely. Will be ordering from here again. Was this review helpful to you?

What was on “Special” this month June 22, 2022 : Paul from United States   Have ordered a lot of stuff from MAS over the years and am  a very happy return customer. This is the first “complete” upper I’ve purchased and it looks very nicely done—and all I have to do is pin it on and go.  The bcg and ch appear to be top notch.  No corners cut—-Very pleased.

Groundworks is the way to go June 7, 2021 : KURTIS from Delaware, OH United States   I got one of the short pistol uppers a few weeks ago and had to turn around and do it again for a rifle upper. Fantastic build, I like that the handguard feels substantial. Can't wait to take it out. I'm sure it will shoot well Was this review helpful to you?
