Needs duct tape Don't tape down the pump lever at the same time!!
On a more sensible note, I don't think you could scope the 601 as you need access to the loading port - the scope would have to be far too far forward to see through, or so far back you couldn't get your head down to the stock.
I suppose a forward-mounted pistol scope might work..... but why do you want to cheat, anyway?
