I've been looking at a Knight DISC 45 cal which is at a local pawn shop. It's been there forever with a asking price of $250. It comes with a TC Scope.

I know nothing about the DISC other than what I read here. The bolt seems to be tight to a point you can't open the action. Is there a lever or switch that must be thrown to open the action or is it just locked up? I'm interested but don't want to buy something that's junk. What else should I look for and any ideas what it's worth. What tools do I need to look at the barrel and pull the breech plug?

On the outside it looks pretty clean.

Thanks,
