Flip Up Lens Caps

Top quality custom fit lens caps for rifle scope eyepiece and objective lenses from the legendary Butler Creek & Vortex Optics 

See Eyepiece models for the end you look through (ocular) and Objective models for the "big end" of the scope (Objective)

Fitting Guide - The caps are described with their diameter measure in mm and inches. This refers to the size of scope they will fit - OUTER casing diameter measurement - NOT the scope lens size itself. Most scopes typically add from 5-15mm of diameter over their stated lens size. So be very precise with your measures.

 


Vortex Defender Lens Caps -
These are more flexible in sizing. If you have a scope with a 40mm lens for example, check out the size 40 to find out what the outer lens size diameter range is. If you are within it you have a fit.
