JR couldn't have said it better. You'll have more things to worry about than where you're going to store your rifle. And as far as NAMI goes, the physical they give is more in depth than the one that is usually given at MEPS (at least it was for me). You will read on this site several posts that claim the eye tests they give are unfair and that they are out to 'fail' people. That is a bunch of BS. If you meet the requirements you pass, if not you fail. Blame MEPS for not catching it earlier, not NAMI.
Good luck
