December 20, 2019 : Trevor Hall from Woodstock, GA United States   I put together a pistol used an h1 buffer with an Sb adjustable pistol brace, I’m running a suppressorand I’ve put a couple hundred rounds through and have had no failures. Very happy with the quality of The upper and the rail, in my opinion very good quality build. Very glad I went with the MAS NERO rail. Was this review helpful to you?

Excellent Company September 15, 2019 : Don W. from Houston, TX United States   MAS Defense seems like an excellent company.  I got their name from the AR15 forum, looked at their products and their upper was exactly what I was looking for.  Service was prompt, the upper was packaged well. I'm still in the gathering stage of my build so I haven't shot the upper yet however I did put it on the lower and it matched perfectly.  Fit and finish is excellent, can't wait to shoot it.
