Rifle Scopes picatinny base for a pre 64 la. mag ?

Re: picatinny base for a pre 64 la. mag ?

John, as long as its not pre war it should be factory drilled and tapped but I think that the spacing on the rear is different between the mag. actions and the standard ones. I can find out for sure tomorrow.
