5 of 5 Great Upper July 25, 2014
: Alan L  
I bought this upper with the CMMG 8" barrel and it works great. Fit and finish are great and accuracy right out of the box without sighting my Eotech in was great, very tight. I was hesitant atfirst as I had not heard of MAS, but I will order again. Shipping was fast. I am impressed.Alan

5 of 5 Great upper!! Quality products here. January 30, 2014
: Michael H  
Bought this upper for my first AR pistol build, ever since the sb15 brace came out I've been eyeing them up. Well I stumbled upon this store when I decided on 300aac. The upper came in 6 ds from payment to delivery. Fit and finish is top notch, took the pistol to the range and shot 100 rounds through it. Everything cycled perfect. I was happy enough to order another upper for another build. A+ masdefense
