12Bravo20---check out some of the no drill scope mounts for the Mk ll.
I have looked at the different "no drill" mounts. I am thinking that I want to go with a micro red dot/reflex sight and found a mount that will work.

I have tried my Swampfox Kingslayer micro red dot on my S&W 22A and really like it. I have also used a Bushnell TRS-25 on the 22A. Size wise I will probably go with something with a RMR footprint for my Ruger.
