ok just calm down.
you could look into "buymilsurplus.com"
i have lost a pins on my mosin and had to buy replacements (stupid trigger pin)
they have good prices.
and something to say about the brass stacker. i have one and you may need to get new screw threads that lock the mount on. the ones brass stacker give you arnt very strong and can snap on occasion.
also for best scope mounting you will need low rings, and may need to cut, the front off the mount , so as to drop the scope lower, for better sighting.(what most have done but just something i thought i should point out)
If zombies, i have gone for big guns, will return soon !
