5 of 5 Great company to deal with September 11, 2023
: Tyler Randolph from White Rock, NM United States  
Ordered the upper and had a quick response on a part they didn’t have and they explained some things I did not know about the 300 blackout pistol and carbine gas systems and got it shipped out fast. Upper came packaged nice and secure and all parts are very nice quality. I will buy from MAS defense again for sure! Very impressed
