It is a Hungarian copy. I read someplace that the Hungarian maker, FEG, used FN tooling. They sold the pistol in the US to KBI, it was also sold as Mauser, and as some other name in Israel (but I believe with a different barrel or slide). Thanks for the info, it gives me something to look for. I would not have thought of the barrel being in two pieces. As regular as the line is I bet that you guys are on the money. It is perfectly straight and right where the cartridge rim headspaces inside.
John Traveler, I don't know if you remember, but you told me how to smooth up the bolt on my rifles with moly grease. I was skeptical months ago, but did what you said, working the bolt 1000 times. Everyone that handles the M70 (I did a M700 too) comments on how great the action is for such a cheap rifle. Thanks again.
