Just curious to know how many on here own a Ruger MK II semi-auto .22 rimfire pistol. I have owned a Ruger 22/45 for a few years but I ordered a new Mark II Competition with slab sided bull barrel. I am planning a few modifications on it including Volquartsen grips and compensator, extended magazine and bolt release levers, Weigand' s scope rings and Weaver style base and I' ll put my Tasco red dot on it that I had on the 22/45. Can' t wait to get it and try it out, I' ve heard the Comp. model is a great pistol. Anybody else had any experience with one of these?
