I have been using Mas defense components for years now. You cannot beat the value you get with their products without spending a whole lot more. Everything has been reliable and consistent.

5 of 5 Great upper! November 10, 2018
: Shawn Lanier from Elkview, WV United States  
The complete uppers I saw on the site looked great for a couple of builds I am doing. I ordered 1 to check it out before buying another. I received it yesterday and mounted it immediately. It looks great! The amount of parts I could melonite was a plus. The website upgrade selections was a nice feature. Buying another soon!

5 of 5 Competitive price with better barrel selection April 1, 2018
: Justin G  
Finding .300 BLK assembles uppers in 1:7 twist proved difficult, thankfully MAS Defense allows you to pick and choose among various lengths and finishes. Many competitors in this sector only offer 1:8twist. Upper arrived inside of one week. Quality seems great. Havent got out to shoot but am impressed with the finish, the hand guard is slim and comfortable. The flash hider was timed properly. For the money I couldnt be happier.
