I would help you if I could but I'm thinking the problem is the level you're asking for. Why would people be roaming around with 55 gear? And better yet, why are you looking for 55 specifically?
I understand what you're saying but surely someone must have it somewhere... right? Also the reason im looking for them is because my Pistol build on my Gunzerker is now crappy with lvl 50 pistols against lvl 56 ememies.
