Butler Creek 30210 Flip-Open Objective Scope Cover Size 21 44.10mm Black Polymer

The Butler Creek 30210 Flip-Open Objective Scope Cover in Size 21 is a hinged lens cap built to fit rifle scope objective bells measuring 1.735 inches (44.10mm) in outside diameter. The flip-up lid opens with a light touch of the release tab, so your optic is ready the instant you shoulder the rifle, with no lens cap to fumble with or lose in the field.

Made from a flexible, weather-resistant black polymer, the cover slips on the objective with a friction-fit collar that grips the scope housing without tools, rings, or adhesive. An ambidextrous hinge and tab accommodate both left- and right-handed shooters, and the seal is weatherproof tested to -40 degrees F to keep dust, snow, rain, and debris off the front lens during transport and storage.

Butler Creek's flip-open line is sized by the outside diameter of your scope's objective bell. To confirm fit, measure the outer diameter of the objective housing with calipers or a ruler and match it to the 44.10mm / 1.735-inch specification of this Size 21 cover. This listing is for the objective-end cover only; matching eyepiece covers in the Butler Creek line are available separately.

Manufactured by Butler Creek, the 30210 is a current-production optic accessory and ships in new condition.
