F/S K-80 34" Unsingle Barrel w/ 1/2" Delrin Add-On Rib. Barrel was re-blued by Krieghoff ($325.00) before sending it to Dennis DeVault for the Delrin Add-On Rib ($375.00). It was then sent down to Tom Wilkinson for Backboring ($500.00) to .740 and (3) Titanium Chokes (.023/.030/.036) another $420. If you have a K-80 with an adjustable comb, you need only add 1/2" spacers and you will be shooting in a "heads-up" position, similar to a Trap Special. Priced at $2,850 plus shipping. PM me with any questions, and as always thanks for looking.
