I measured my Vortex sunshade with micrometers and got a reading of 2.206" Which cap should I buy for it? I emailed Vortex but, never received a response.
read the 3rd post down i believe by "fordsoldier" and look for the mm size and then the corresponding # next to it is the size you need when you go to buy them. THis is no way a correct example but 51.25mm= #24 or something like that.
