These new flip-open scope lens covers from Butler Creek will give you the same great lens protection as the standard covers we have carried for years. The Multi-Flex covers have additional flex in the collar so a wider range of scopes can be covered with each size. The tight, flexible skirt provides a custom fit for multiple scopes with the same features as the standard flip-open covers. Use Butler Creek Multi-Flex Sizing chart for cross reference to proper size.
