5 of 5 Always A+++++ 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!

5 of 5 Bang bang 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.

5 of 5 Just awesome 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.
