Top quality build November 19, 2023 : Sterling Deslatte from Austin, TX United States   The quality and finish of the 300 blk upper I purchased are top notch. Just shot it today for the first time I will only be buying uppers with Mas logo on them from here on out. Was this review helpful to you?

300 blackout September 14, 2023 : Darryl Barnhart from Swartz Creek, MI United States   I received my SBR very quickly after I built it on line to my specs. I will be shopping for more masdefense products in the future. I haven’t got my tax stamp yet so I am unable to shoot it. Will keep you posted when I’m able to fire it. Thank you masdefense.

Great service MAS Defense October 12, 2022 : Mark Lefevre from Snowflake, AZ United States   MAS Defense went well above my expectations from the prompt emails back from my questions to even giving me a call when I still had a few other questions before placing order. Then my order placed with it being shipped out the same day had me floored. Soon as my 300 blackout upper arrived I had to check it out with everything looking perfect. Now I’m looking to put together an AR10 and this will be my place to come back to make another purchase. Was this review helpful to you?
