The BUTLER CREEK #20180 Flip Open 18 Eye is a premium flip-up eyepiece cover designed to protect your riflescope from dust, dirt, moisture and scratches while keeping your optic ready for immediate use.

The spring-loaded hinge folds the cover completely away from the sight picture, allowing fast target acquisition without obstruction. The silent spring hinge design makes it suitable for hunting, sport shooting, tactical use and outdoor applications.
The flexible friction mount creates a secure fit around the eyepiece while the semi-O-ring seal helps keep dust and moisture away from the lens. Built for demanding outdoor conditions, the cover provides reliable protection in changing environments.
Made from durable polymer, the Butler Creek Flip Open 18 Eye combines strength, lightweight construction and long-term reliability. It is ideal for hunters, sport shooters and anyone looking to protect valuable optics.
