5 of 5 The best deal going for a upper April 11, 2019
: Allen Vaillancourt from Hale, MI United States  
Purchased a MAS 300 blackout pistol upper. It was a blem sale. This is a super quality upper for the price. As a blem goes, you wont find it on the upper I received. I don't see how they can make any money selling these quality uppers. Fast shipping and packaged better than anything I have received from other online companies. I will be making more purchases from MAS Defense.

Excellent fit and finish. Bought as a blem item, but the blem is hardly noticeable. Runs great, accurate and reliable thus far. Great upper and the guys at MAS are great. They go out of their way customer service wise. Have bought there before and will do so in the future. Buy from these folks with confidence.
