I've been in Rob's as well. Most of what was said above it true - it does have a bit of a pawn shop feel to it. Also, I suggest that if you don't like the smell of smoke, steer clear of this place. The shop reeks of it.

Rob's was unfortunately involved in a smash and grab robbery a few months back :-(

If you are interested in military rifles/pistols, I don't think this is the place for you. I did see an M1 and a Moisan Nagant, but they didn't have a ready stock of rifles on hand. The people behind the counter were personable though and willing to help you locate what you are looking for.
