Helpful Positive Review Size 47 for Ares ETR by someguy, Verified Owner, March 22, 2020

Helpful Positive Review Butler Creek Scope Covers by Legacy Reviewer, August 4, 2008
I have Butler Creek covers on all of my rifle scopes. They work and protect the lens and keep them clean/ scratch free. Why buy an expensive scope and look through scratched/dirty lens? They just make sense.... Pros: Value and function Cons: Sometime...

Please note that the chart provided by Butler Creek is a guideline. To ensure a proper fit of Butler Creek Scope Covers, you must measure your riflescope with a micrometer or a caliper, and then choose the size that offers the closest fit. Sorry, due to the inventory system here at OpticsPlanet, we do not have access to riflescopes to measure them for you. We suggest you order scope covers after you receive your new riflescope.
