I'm starting out with the open sights, but will be mounting a scope eventually. I can see why the raised mounts are necessary. What's everyon'e opinion on QD bases? I was thinking it would be nice to drop the scope in a hurry, but just about anything from a coin to a screwdriver, to the back edge of a knife will fit in the slot of most mounting screws. Will they stay locked up tight (the QD's) and will the scope and ring assembly hold point of impact?
