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.

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.
