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.
