5 of 5 High Quality Upper at Great Price! February 18, 2021
: Brandon from WY United States  
This is likely the highest quality upper I have acquired for under $400 bucks. Looks great, fits the lower well and extremely light weight.  The logos are a nice touch. I've mounted the upper,  installed the BCG and everything functions smoothly and as intended. Still need to test it at the range, but so far...so good.

4 of 5 completed upper July 30, 2020
: Erick McFarland from Charlotte , NC United States  
Upper received as described intact without any issues. Fit my Aero precision lower perfectly. Will definitely buy from Mas Defense again. Haven't put the upper into action just yet is the reason for not giving a 5 star rating.

5 of 5 MAS .223 11.5” Upper combo July 12, 2020
: Nicolas Fernandez from Sparks, NV United States  
I purchased the 11.5” upper barrel combo and for my first pistol build after a recommendation from a friend. I emailed with shipping questions and got a quick reply. Purchase was trouble free and it arrived earlier than expected! I will definitely be a returning customer when I start my second build! I already recommended MASDefense to a coworker for his build.

5 of 5 Excellent Product May 22, 2020
: Jakeb Davis from Central City , KY United States  
Even though I haven’t shot this upper on my build yet, I am completely happy with the quality of the product. MAS Defense clearly take pride in the products they sell. I will try to make another review once having some rounds put down range through the upper.
