This is for the new version of the Sidewinder SF30 scope .
This scope has a stock sidewheel that has three screws in spokes that jut out from the stock hub that the wheel fastens to. This new wheel will replace both wheel and stock hub.
Please see the picture of the scope to verify your scope model.
This wheel fits the Hawke Sidewinder 30 IR scope, not the Airmax 30 and ED , or the old style version of the Sidewinder with compression rubber. This is also a different model than the newer Sidewinder H5 scope.
