Query: Worked for a while

If you intend to do any shooting whatsoever, this is not the scope for you. Upon installation, one of the mounting screws began to twist out. After twenty or so shots, the cheap plastic retainer on the front objective lens actually snapped in two. Without this retainer the sight became utterly useless. I am dead certain the scope never stuck anything, but rather it broke from simply firing my low powered target gun. If you look at how flimsy the parts are on this scope it will be obvious just how long it will last. Don't throw your money away. Spend five bucks more for something better.
