5 of 5 G22 frame and rails/awesome customer service February 25, 2025
: Drew Spicer from Bucks county, PA United States  
I got my order after a decent wait, but that wasn't mas defenses fault uses misplaced a good amount of frames and a 2nd one had to be sent... I got exactly what I expected and the frame itself is actually a little nicer than I had thought it would be... pleasantly surprised. Thank you Junior for making it right and sending me the 2nd shipment... I've been waiting to start this build, like a kid waiting for christmas.... Cheers...

3 of 5 Jig issues/defective jig August 25, 2024
: Aaron Peloquin from Chippewa Falls, WI United States  
I got the product fast, but I am having Jig issues. The FCG group pin holes are sized differently and they’re not supposed to be. So my jig is defective. I didn’t really want to complain. I’d rather just get the work done, but for all my inquiries, I get referred to someone else, ghostguns.com or something like that, but they sure don’t like my questions because they’re not allowed to legally answer them apparently. I can’t get any of my questions answered because it would have to do with working around the jigs flaw. They say oh well, we can’t tell you how to work on that it’s not an they say oh well, we can’t tell you how to work on that it’s not allowed by the ATF.  All this and no one has bothered to just replace the product. And it’s like a $35 product.

5 of 5 Polymer jig August 5, 2024
: from Colfax, WI United States  
Was like others a little skeptical as I've not heard of MAS Defense before. Jig was decently priced and I received it very quickly.  Definitely will be looking to them for further buys.
