4 of 5 Some problems October 10, 2023
:  
So starting out none of my glock mags would sit properly and it didn't matter which brand of mag it was none of them would sit properly. So to fix this I had to switch out the pin that holds the mag catch for a thicker pin so it wouldn't move around as much. The pin i used is about the same diameter as the bolt catch pin that came installed i just had to find one with the correct diameter and a little bit longer. i also noticed when i took the mag catch off that there were a few burrs so i just dug those out real fast. Then i had to file down the AR-9 ejector because it was sticking out in the mag well and also preventing mags from sitting properly... after all of that it now accept all my mags perfectly. I am still very happy with my purchase i just thought i would give you guys some feedback so maybe you can fick these problems in the future.

1 of 5 80% lower 9mm June 1, 2023
: David Cole from Boone, NC United States  
Seems decent but does not fit my mil spec jig by broken arms and the mag release is catchy on retaining the mags. This is a non returnable item!!

MAS Defense Reply: David, these lowers will fit most jigs that accept Mil-Spec lowers like the New Frontier Armory jig. I don't think we have ever had any customers have any issues with jig fitment. The product description states 80% lowers are not returnable items. I apologize for the inconvenience.
Thank you for your business and your feedback!

5 of 5 Looks great!!!!! January 24, 2023
: D W from NH United States  
I needed an FDE lower because I found a clearance billet 9MM FDE upper for $39 on clearance on another site... Always worry that companies do not use the standard Cerakote FDE color and things are not going to match... looks perfect... very unique design... and great price.  could not ask for more...

5 of 5 Best price by far, insanely fast shipping. January 18, 2022
: Austin Krudup from Towanda, PA United States  
I'll give if 5 stars because as a whole this company is worth it. As for the product, it wasn't the worst thing I've ever seen but definitely not the best. It came with a small blemish near where the safety selector. Also the safety selector detent hole was not drilled deep enough. And there was no way to tell this until it was already milled and drilled so therefor returning for a new one was not an option. I'm sure it was just an innocent mistake which happens.
