Scope models vary across years. PLEASE CHECK THE SIZE OF YOUR FOCUS KNOB BEFORE ORDERING.

If you order for a scope not on the list please let me know if it fits.

The internal cylinder of these wheels is flat. They may be unsuitable for scopes with cone shaped knobs or knurls. I am happy to advise if you send me a photo of your scope.

Made from tough ABS plastic using 3D printing.

I dispatch most orders within day and the default is first class mail. Please choose second class if your purchase is not urgent.

I can make these to fit any size. Please search eBay for model first. If not found and you wish to help me expand my range then I will need the following information: Scope brand and model, focus knob outside diameter (accurately measured with a vernier) and a side and top photo. Also any other relevant measurements.
