Forum:All seeing eye skin and Bunker head

So I have been fighting threeshers for about a week now on all three playthroughs and I CAN NOT get the I guess ULTRA MEGA SUPER DUPER INCREDIBLY RARE skin to drop! I really want it for my siren. Same goes for the dumb ass Bunker head. Willing to trade whatever I have that anyone wants... even though Im certain the lot of you already have better weapons than I do, but I don't even care anymore been at it for days. Or if anyone knows any tips on how to get rare things to drop or how to farm that'd be great. My name is ( iiiegalinternet ) on Xbox hope so hear from someone soon... anyone.
