Forum:+n Rare Find Mod

Hey all, new to the BL 'Verse. I've got my character up to level 55 or so and saw a class mod yesterday with a +2 rare item find team label. So my question is, will that work on a single player, and if not are there class mods that do the same thing for single players? I'm trying to get some more kick-ass weapons, and more importantly shields. I gots to kill that Crawmerax bugger. Happy playing.
