Exactly what I needed
March 8, 2022
: Jeremy from Pittsburgh, PA United States
This spring was exactly what I needed for my pistol build. Also, shout out to the customer service team to help me with my order when I accidentally ordered three! Great service!

It works
December 14, 2021
: Bradley Thayer from West Plains, MO United States
Appears to be of good quality but I'm no sitting expert. I'm not disappointed that's for sure.

Buffer parts
October 11, 2021
: C. J. from VA
Bought an SBA3 pistol brace locally at a great price. It came with a 6 position buffer tube, but no hardware, spring or buffer. MAS Defense had everything I needed.
A MAS Defense complete buffer kit will come in at less than the sum of all of it's parts, but if you just don't need the tube, the parts are available.
