Has anyone used a Ruger Mark III with reddot or other optic? I am interested in a Mark III with a rail to mount a holo sight. Is there any interference from ejected cases? Is there any setup that is preferred? I was going to buy a Ruger MKIII 22LR 5 1/2" Blue target model. It is not for competition, only practice at the range. Words of wisdom greatly accepted. I have a half dozen large caliber handguns and a Ruger MK I. Sometimes you just want to plink.
