The Butler Creek Flip-Open Objective Scope Cover, Size 23 (1.760-inch / 44.7mm), is a Butler Creek flip-open cover for the objective (front) lens of a riflescope (Butler Creek part no. 30230). It is cut for a housing diameter of 1.760 inches (44.7mm), so it is a fit-by-measurement part rather than a universal cap. A flexible friction sleeve slips over the scope to give a waterproof, airtight seal, and silent spring hinges let the lid open with a touch of your thumb. That makes it a practical way to keep rain, dust and scratches off the glass on a hunting rifle or a range scope without a loud snap giving you away.

Key Specifications

• The chart designation is Size 23, the number Butler Creek uses to match this cover to a scope housing of this diameter.
• The cover is sized for a objective bell of 1.760 inches (44.7mm), so measure the outside of your scope housing before you order.
• It protects the objective end of the scope; Butler Creek lists eyepiece covers under separate size numbers.
• The seal is waterproof and airtight, which keeps rain, dust and grit off the glass between shots.
• The lid swings on silent spring hinges, so it opens without a noise that could spook game.
• The lid opens with a touch of your thumb, which gets the lens uncovered quickly when a shot presents itself.
• The cover is rated to perform from -40 to 120 degrees Fahrenheit, so it keeps working in cold-weather hunts and summer range days.
• It is built from a heavy polymer cap, a flexible rubber housing and steel hardware for durability in the field.
• The cap opens vertical or locks down flat, so you can keep the lid out of your sight line.
• The flex-fit sleeve is a slip-on friction fit, so it mounts to the scope without tools.
