I just installed the Magpul grip and discovered the front of the grip will not sit absolutely flush with the trigger pack (unlike the Yeti grip I replaced). I get that I could loosen the two screws on the grip and likely force it forward enough to eliminate the gap. However, the result of doing this seems to create a gap at the rear of the grip, as well as, cause potential difficultly with the removal of the trigger pack. I guess the other option would be to remove a little material from the grip channels to allow it to move a bit more forward without creating a gap at the back. Going this route might still create an issue with the trigger pack removal. I think I will leave well enough alone. Sorry if I'm just reiterating the obvious.
