5 of 5 Mas Defense experience December 22, 2022
: Jesse Mullis from Peachland, NC United States  
I got flagged buying my upper because my daughter got it for Christmas which is great thay they care about people instead of a sale . But a quick phone call directly to a real person fixed the situation and I had beautiful upper in just 2 days . Best customer service I have seen and qaulity is amazing. I have purchased from alot of place there's good customer service buy this was unparalleled service . I have told everyone about MAS defense.  Great people thank you .

5 of 5 Perfect!!! October 23, 2020

I could not ask for more!! This upper is incredible, it looks like it should be triple the price. I appreciate that MAS Defence keeps there prices affordable. I also own one of their 300 blackout uppers, and that one is also amazing. I love the fat handguard on this thing, it is surprisingly light weight for it's size.
