    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 TechnoPro - Optics Online, we do not have access to riflescopes to measure them for you. We suggest you order scope covers after you receive your new riflescope.
