All you will need for any build
February 7, 2018
: Bill A
The specs on this upper are perfect. I put it on my PSA, A, Colt, and Spikes lower with a perfect tight no gap fit. I haven't got the barrel for this build yet so a tried a BCA I had laying around to check fit and it was perfect and tight. The finish is great, everything works as it should. The price from MAS was better than I found anywhere. I will look to them first for all my future needs and recommend anyone to do the same.

Aero Complete upper
July 23, 2016
: Justin A
I'm really happy with this piece. It pairs well with my A Manufacturing lower, with very little if any wobble. Have already recommended to one friend, and would be likely to do the same for others looking to build an AR platform.
