Support for Unlisted Optics

I have an optic that isn’t listed on the website. Can you support it?

Possibly — but we’ll need a little more information first.

1. Check the eyepiece shape: Your rubber eyepiece should be straight and non-tapered. If both sides are parallel, there’s a better chance we may have something that works. Please reference the images below for examples of a straight vs. tapered eyepiece.
   
2. Measure the diameter: Using digital calipers, measure the outside diameter of the rubber eyepiece as shown in the image below. Then send us:
   • the measurement in millimeters to the nearest tenth (e.g., 42.3 mm)
   • the brand and model of your optic

Once we have that, we can search our parts catalog and see if we may have a compatible option. We’re happy to check, but we can’t guarantee compatibility for optics that aren’t currently listed on our site.
