pre-Bushnell Trashco (what a scope!):

I actually liked this scope until it let me down.

It's entire life was spent mounted on a 10/22 with a heavy barrel;  I guess it just couldn't take the strain of recoil produced by a .22lr.  Goes to show, you get what you pay for.  I find that many cheap scopes look very good when new and only after you've had them a while do issues begin to show up: wandering poi, tracking issues, durability, etc.
