I have owned a few Knight disc rifles. The disk is a pain in the butt but no complaints otherwise. The only Knight that didn't shoot for me was the original 45 cal. Personally, I would never buy a used muzzleloader unless I knew who had it or I was allowed to shoot it first. Sadly, most folks I know take very poor care of their MLs. I can't recall ever seeing pitting in any of my MLs.
The Black Diamond came for consignment while I was looking at the Knight, the seller wanted to deal direct in the shop in front of the owner. I declined, and came back later, which went over very well with the shop owner. However, his consigned BD was spotless inside and out, the tools were present and bagged, the scope install was perfect, and you could tell from the care that the owner went an extra degree to take care of his firearms. The owner's book had all of the purchase data card filled out. The proverbial "only shot on Sunday" rifle...
