I've got one with the illuminated reticle on a 1942 round receiver Mosin 91/30.
I've got it mounted on a no gun-smith scout mount, with the rings that were included with the scope.
After about 2 or 3 hundred rounds it's still holding zero and hasn't had any problems what so ever.
These are fantastic diamond in the rough scopes. For the price you can't go wrong. I think Marstar stocks them.
