Butler Creek 30040 Flip-Open Scope Cover 27.8mm Objective Size 04

The Butler Creek 30040 Flip-Open Scope Cover protects riflescope lenses from scratches, moisture, and debris while providing instant access when shots present themselves. This polymer scope cover eliminates the fumbling and delays associated with traditional lens caps that must be removed completely.

What Makes This Different

Unlike standard screw-on caps that can be lost or dropped at critical moments, this flip-open design stays attached to the scope via a spring-loaded hinge mechanism. The cover opens with a simple thumb press and automatically locks in the open position. Butler Creek's sizing system ensures a precise fit on scopes with 27.8mm objective lenses, preventing the loose fit issues common with universal covers.
