Top notch brace - Maxim Defense Industries PDW Brace for MPX

To me the fitment is right on dispite what others have said.You have to wiggle the brace past the first grooves and I was able to push it down almost half way with my hands. It is a really snug fit which is good to me. Then I used a hard plastic flooring block used for laying laminate floors with a rubber mallet to tap rest of the way. Make sure you line up the hole perfect or screw won't go in to secure. Looks are awesome. I have a sb tactical brace but like Maxim much better. Better butt pad contact area. Better deployment mechanism. I'm very happy with my purchase. Get these while you can. Lol
