Don't use my O/U barrels. Tried doubles a few times but wasn't fun to me so I don't need them. They are from my first K-80 bought from Hal Dupont at the 1991 Grand. The ejectors have screws in the sides. The mid bead is ivory died red.Front bead is a standard K-80 bead. The barrel hanger is a #6. They do have nice clean smooth bores. At a charity shoot someone picked up my gun and must have threw it back in the rack because the rib had a slight dent. I had it repaired by a good gunsmith and I was having a hard time finding it now, but it was repaired. Bluing is very good with one small imperfection,of course it has the normal scratching around the area that is hidden by the front wood. They have Briley thin walls and come with Full, I.M., and Mod. chokes. Only these three. From the sixteen to the twenty the bottom barrel really smoked them when I was doing my part. They are ported and I beleive the porting is factory. That is the way they came with the gun. Despite my sign on name these barrels do not have bulges! Thanks for looking, Bulge.
