5 of 5 Great Quality ! Great Customer Service! November 19, 2019
: Alex C from North Miami, FL United States  
Received the upper fast and packaged well to ensure no damage. When I finished my build I had issue with ejections. I contacted customer service Zach contacted me right away, walked me through a few trouble shooting steps and then he determined I should send it back along with my bolt carrier (not purchased from mas defense). They tuned and adjusted it and even sent me a video of it being test fired. Shipping back to me was also fast. Took it right away to the range and it went through 120 rounds NOT A SINGLE MALFUNCTION. The guys at Mas Defense are a true class act. I will definitely be be purchasing from them again.
