5 of 5 Customer service/shipping December 9, 2022
: Tyler Miller from Round Rock, TX United States  
Mas Defense has always done me a solid.  Their products have yet to fail me.  From finding what I want to it hitting my porch, their service is top notch!  When are we going to see any adjustable gas blocks y'all?

5 of 5 10.5" 5.56 upper September 1, 2022
: David Stevenson from San Antonio, TX United States  
I'm really pleased with the quality of the upper and the shipping process. The only small gripe I have was with the timing of the muzzle device, which is off by only a few degrees but it is noticeable. I will have to fix it myself. Not a huge deal considering the quality of the parts vs the price that I paid. Overall very happy with my purchase and I am already planning to buy more from MAS.
