The Butler Creek 30450 Flip-Open Objective Scope Cover is purpose-built to shield your optic’s objective lens from dust, moisture, and debris. Custom fit for 61.20mm objective housings and sized as a Butler Creek "45," this lightweight polymer cover forms a watertight, airtight seal while remaining easy to deploy with a simple thumb flick.

This slip-on cover is ideal for hunters and precision shooters who need clear glass the moment a shot opportunity appears. The fast, silent hinge design lets the cap spring open without distracting movement, helping you stay focused on the target in harsh weather or low-light conditions. Tested down to -40 degrees Fahrenheit and weighing less than an ounce, it offers dependable protection without adding bulk, reflecting Butler Creek’s long-standing reputation for practical, field-ready accessories.
