Hello all, I found one of these recently. Does anyone know what to repair it with, other than more Trail Carbines; and where do i find more of these guns?

Thanx, Robbie

Unless you have Jury Rigging, all items are repaired by the same (or very similar) items. Trail Carbine is repaired by Trail Carbine.

Or Repair kits.

Take it from me. Take any Duct Tape and Scrap Electronics you come across. Weapon Repair kits are your friend.
