Caldwell lead sled or higher mag scope?

[trigger-finger]

Hey Trig. We see a lot of zeroing issues in here from the owners of the Nikon package scopes. What does it say on the scope? I don't think it is a Prostaff model or it would say so.

Yea, it is a Prostaff 3-9x40 BDC

Scope is OK, but I've done research and hear rings are not. However, all the scopes I'm looking at have 30mm main tubes so if I replace rings now they want fit on knew scope.

What's slipping is the big thumbscrew which holds rings to base keep loosing. I used pliers and tightened it pretty good and bore sighted scope.

this is it. needs tool to adjust turrets.
