Additional Details ------------------------------ Product description: 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 tight, flexible skirt provides a custom fit for multiple scopes with the same features as the standard flip-open covers.
