What would a 34" single barrel factory choke tube K80 be worth in outstanding condition? Also what would a 32" o/u barrel in same condition with briley thin wall chokes be worth? Each barrel has 5 chokes. They are both step rib barrels and look new in every way. Thanks for the info as i may be parting out a K80 and keep the receiver. I am hoping 2500.00 each.
