Knight disc .50 call muzzle loader with the extreme conversion bolt. I’ve owned this muzzle loader for 20 years and taken good care of it. I am the second owner. The rifle came to me with some pitting in the rifling just ahead of the breach plug. It is where the powder would be when loaded. I do not believe it affects accuracy and most people would never know it’s there but do want to be forthcoming that it is there. Other than that, the rifle is in very good shape. Comes with original factory box, original “orange disc” bolt, red extreme primer modules, orange disc primer modules and scope base. Will ship direct to buyer. Great muzzle loader for the price. $250 shipped TYD PayPal F&F or add 3%. USPS MO works too.
