My guess would be that if you have to farm this project out it will cost more than any configuration of the Ruger .22 caliber pistol that is currently offered and have very little resale value.Need someone who can rebarrel a MK II Ruger.
I have a chunk of barrel from a 52 Winchester I would like turned and fitted as well as drilling and tapping for a scope mount. Ideally they would be in Missouri.
