5 of 5 Completely Satisfied February 1, 2023
: Luther Workman from Bluefield, WV United States  
My upper arrived in perfect condition, and the quality appears to be well above its price point.  MAS DEFENSE has been a great company to deal with.  This was my first time ordering from them, but it won’t be my last!

5 of 5 Can't say enough April 28, 2022
: Doug from Fuquay Varina, NC United States  
Purchased a 16in 300 blk out upper receiver from Mas defense , I had a few issues from the start so I emailed customer service and we were able to  narrow it down to the ammo, I can't say enough about the product and the customer service, both are outstanding, I emailed 3 times and got a helpful and knowledgeable response from customer service all 3 times. Mas defense makes a quality product and they definitely stand by that product , thanks again Mas Defense.
