I inherited this from my father when he passed in september. just trying to learn about it and learn its value. it is a knight muzzleloader mml inc mk 85 pat. 4700499 s. 35617

From what I can see it does appear to be a MK-85. I can not read the marking on the right side of the barrel just ahead of the receiver and I do not know enough about the serial # breaks to tell you which barrel it has. Most likely a Green Mountain but not positive.

It's a good gun. One of the classics.

You will love shooting the mk85. Stay away from blackhorn powder and give triple 7 a try. I shoot 110g equivalent with t7 and use a 260gr nosler pistol bullet. Mine shot powerbelts very accurately but they were lacking in the hunting dept.

I dont see a set screw for the plunger assembly so im guessing its not a early model MK85. It looks like a bit later model and possibly a Green Mountain barrel MK85 Predator. Black and SS were called Predators. Not sure about the camo models.

super nice gun....i got one for a hundred and one for 250 dollars . hard to say what there worth in great shape you might get 400 for it if you find someone looking for one
