300 blk complete upper Thursday, September 3, 2026 : Kevin Gaudet from Newbury Park, CA United States   I have purchased 3 complete uppers from mas defense every one has operated and functioned perfect. I went with 300 black out. This one took the cake for me I chose the Fde Upper with all the options including flash can, and the gold Bcg Absolutely beautiful . Everything about it is done to perfection. If I could give 6 stars I would. Shipping was super fast customer service is really easy to deal with. Highly recommend. Thank You again Was this review helpful to you?

Always A+++++ Thursday, February 4, 2021 : Chris Behm from Plainville, CT United States   Amazing 300blk upper, but no one ever hit me up about possibly changing my A2 birdcage prior to shipping for a flash can!  I emailed you guys to no avail! Was this review helpful to you?

Bang bang Wednesday, July 29, 2020 : from MD United States   Only put about 200 rounds through so far, but it does exactly what you want. Shoots straight (at least as far as my talent will let me), doesn't do anything funny, feels solid, and shipped very quickly.  Highly recommend. Was this review helpful to you?

Just awesome Saturday, June 20, 2020 : Justin Elliott from Katy, TX United States   I bought from a bunch of places and then , after finding out I was short some parts... my experience with Mas Defence was so far and away better than all the others, i bought the remaining parts from them. Hey, you live you learn. Next time I’m full Mas Defence Buy with confidence, quick, consistent, and well priced. Was this review helpful to you?
