Hey, that's a decent collection there dark.zero - counting out duplicates (photos at different angles), I'm figuring you have around 50 or so milsurp rifles. Are you focusing on any particular eras, countries or themes?
IMHO, one only has a problem when you start skipping over life's essentials for a hobby. When you have to skip meals, or a date, or other fun because you're sunk yourself too deep in a hobby, that's where one might want to re-examine one's priorities. And this goes for any sort of collecting. I knew of one guy who was collecting automobiles. Basically the dude had no real furniture to speak of, and could not join the guys out very often - everything was sunk into acquiring and maintaining his hobby. That's where things clearly go over the top.
