For the 1950 M70 .220 Swift I recently purchased. 10X-12-X dull finish steel tube- Leupold, Redfield, Weaver, Stith, Lyman- No Japanese mfg-- German mfg fine if with 1" dia tube- max Bell dia. 50MM- will mount in either Leupold lo rings and bases, or Buehler--I initially posted this in the custom rifles section, so kindly overlook the duplication here. I have given up on E-Bay, its a con game-- the posted price is subject to last minute "upbidding" by shills- just like gun auctions- RWTF
