5 of 5 Another great upper! June 13, 2020
: ANDY S. from BRIARCLIFF, TX United States  
Just got an 11.5" 5.56 upper to go with my 300 BLK shorty from MAS Defense. This is where I get all of my uppers from, and I'm totally happy with that. Really nice builds that function as they should, all at the best prices on the web.
