Yep. I had one that the zoom was messed up. Another fellow on here had one that the erectors were messed up that he gave me. I made one good one out of the. Don't think there is much you can do with the erectors when they won' move the cross hairs. For quite a few years I could dial a few clicks and then tap the adjustment knobs with an wooden handle of a screw driver. Eventually that did not even work though.
