That is ver interesting. I have never seen a scope mounted that way on a mosin before. I guess you learn something new everyday.
No doubt about that, LOL!
I thought it was interesting, to be sure. Been debating whether to mess with mine like that or not. Being a 1938 in my case, there's a chance the sight base is soldered on. Don't really want to do anything that's not reversible. Breaking the original solder, to me, is reversible, but wouldn't be original. As compared to say dropping a Mojo Sight on. May eventually just fabricate my own replacement sight at some point, but will have to wait. Trying to get my working/living situation back to something a little more tolerable, with some time and space to fuss with these things again. Dieing to do some reloading, etc.
Anyway, been studying what's on the web for these guns for a while, so glad I could help.
