: Andy Venters from Monticello, IN United States  
I was referred to MAS Defense by a friend. I really liked the the fact that I could select my own choices. I wanted a SS barrel with Aero upper and was able to get what I wanted with Masdefense.

5 of 5 Great Upper! April 25, 2016
: Joe L  
After a lot of online research and comparison shopping I narrowed my choice to this upper and I don't think I could've found a custom upper that suited my build better. Pricing is excellentfor the quality you get and shipping is super fast. Thanks for a great product!
