I picked up a nice KP514 (22/45 with 5 1/4" tapered barrel) this weekend and would like to mate the upper to a traditional (non-plastic 22/45) MK lower as a general plinking pistol, my question for those much more knowledgeable than I am, will the upper work on a new MK IV lower? Or do I need to find a MK II lower?
Thanks for the assistance, as always, greatly appreciated.
