Great looking products and great service December 1, 2023 : Britton Jones from American Fork, UT United States   I ordered the 11.5 mw8 upper from them and it's by far one of the coolest looking uppers I've owned, the one issue I had was magazines not seating all the way from what I assume was clearance issues. I called and let them know the issue and they sent me a return label and told me they would replace the receiver free of charge! Super great service and I'd recommend them for sure, hoping the new receiver works as well but I know they'd take care of me if it didn't. Was this review helpful to you?

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. Was this review helpful to you?
