From what I've read, one way to spot a fake is looking at the mount screws. If they are not cleanly installed, it definitely is (with mine, the screws look correctly installed... which leads me to believe it may have been installed on a sniper or ex-sniper, since it is a 1942 rifle with matching parts). Another way would be to look at the stock cutout for the mount, and see if it looks fresh. Also, scope mounts are stamped with the rifle's number... fakes, I believe, usually are EPed.
