I’m not familiar with these rifles, other than the Win70 base gun. But what’s with that springy thing on the scope?
Scope mount recoil mechanism. - dan
Its for absorbing the recoil when the gun is fired. The scope slides in the mounts.

Thanks guys. .308 or 30-06? Why is recoil such a problem that the spring is needed?
Because the scope slides in the mounts/rings. With these scopes there aren't any dials on the scope, you sight the scope in by the dials on the rings. The scope is suspended in the rings, not like modern rings which are clamped down onto the scope so it can't move.
That's the neatest bit of history I've seen in a while - thanks for sharing! Wow, that would be much lower tech, wouldn't it? Just an etched reticle in a tube with magnification and/or focus, then these beauties take care of moving it around.
It's only 9:12am, and I've learned my "something new everyday" already.

Thanks for the info, Armedginger! Seems an over complicated solution. I guess it never caught on.
It was a left over from the old scopes built during the 1800s.
Just a straight tube with some lenses. To sight it in you had to physically move the scope.
The USMC for the longest time always was at the butt end of the equipment line, generally using hand me downs and whatever else they could get their hands on.
At one point every target rifle with glass had scopes like this. So yes, it did "catch on"quite well. But technology moves on. - dan

That is amazing! We are so worried about holding zero today that a springy moving part on an old scope must be quite interesting! Not my area of expertise so definitely learned something today. Thanks Dan and Ginger!
Well here is a modern version offered by USO
Here someone is having fun with one on a .22 and other bang sticks

those rings are basically what happens inside the scope nowadays
