I have bought 4 of these, 3 for my VX-II's and one for my buddy who has a new Redfield Revolution.
If you've ever been bumped by your scope for whatever reason, heavy magnum recoil, shooting up hill, real spongy recoil pad, or etc. Put a rubber eyepiece guard on your scope and don't worry about getting hit in the face by a thin metal edge.
These fit perfect, they just thread in to the eye piece and look like it was made on the scope.
