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.

If you can't find a wheel suitable for your scope then please get in touch. I have made a lot of custom fit wheels and may be able to modify a design to suit you.
