Very specific question I need help with. RE scope rings/screws

Hi there.

About a year ago, I got a DPMS SASS. It's a great rifle and fun to shoot, though it is one heavy bastard. I got it off gunbroker, so of course, I was buying someone else's cast-off.

The problem I'm having is that it cam with a Nikon M-308 scope and mount. Well, somebody boogered up the ring mount screws, so the tube is rotating after a few shots, which makes it impossible to hit anything with any accuracy. The screw heads have been stripped out, so I can't put an allen key in there to tighten them up and stop the rotating.

I was only actually able to remove 2 of the screws to begin with, but I figure with a Dremel, I can cut a slot to put a flathead in the other two and yoink them out.

I guess my question is does anyone know if this mount/rings use special proprietary screws that I should replace them with, or will any scope ring screws do the trick. And if any will do, what are your recommendations?

The Nikon people have been less than helpful after 2 different calls, so I figured I'd try on here.
