Does vortex have screws that fit the optic mount for the core? Or vice versa, does m&p have screws the vortex red dot? I am trying to mount my venom currently, and hesitant to lock tight the beveled screws provided by m&p. You said you had to drill/reem yours. I'm not sure I want to do that either. This may eventually get mounted back on it's original picatiny rail mount.
