Does your Model 70 have two barrels Jagermeister? If not, then this subject is totally off-topic for this forum.
We all know you don't own any double guns, and that you do a lot of tire kicking... putting cheap guns on layaway, and then backing out of the deal. Why would any sane person think you would really purchase an aperture sight and then pay for installation? And when your push feed post-64 Model 70 magically turned into a pre-64 Model 70, did the scope mounting screw holes in the receiver also close up? Here's a link to a thread you'd probably like us to forget:
