If I recall, the Magpul instructions specifically mention the use of their own screw. I think the MIAD screw and the standard A2 grip screw are slightly different lengths. I can double check the instructions in the morning. Just a heads up.

Double checked instructions and they advised to use the supplied screw and not the stock screw/lockwasher. The supplied screw comes with locking compound applied at the factory.
Yea, blue locktite. The supplied screw was "fatter" and shorter than the original and did not fit as well as the original. I read the instructions and that's why I used that screw to start with, but that particular screw was not a good fit for my lower, YMMV.
Same problem I had. It was a tight fit, but when I finally muscled the grip on, it was rock solid. Don't forget the blue lock-tite is dried on the threads so it makes the screw harder to tighten, but well worth it. Just make sure its lined up and try using a really large regular slotted screwdriver with a thick blade. After the struggle getting mine on, its the only grip I would have.
I just installed one of these on a Mega lower, the screw was shorter but the same thread pitch and diameter as the on in my LPK. The threadlock they supply definitely made it fit a little tighter, by not like it would feel if I were making my own threads in the lower. You might not have stripped the threads, but you could have done a little unintentional machining in there, tapping your own threads ;) I'm very pleased with the fit of the MIAD. I'll put another one on my new build when it starts.
