Will a BM59 sight pinion fit on a M14? Say you have all the rear sight parts that are USGI but needed a pinion will it work with these parts. Are the tread pitchs the same as USGI or metric?
I wouldn't think so. A click is a click and a meter is a meter. I compared a couple of PB BM 59 pinions with a couple of USGI pinions and, basically, the "BM 59" is where the "M" would be on the U.S. part.Something else I just realized...the BM59 had a shorter barrel than the '14. I wonder if the knob is calibrated differently because of this...
