The BUTLER CREEK MO20130 Flip Open 13 Eye is a premium flip-up eyepiece cover designed to protect your riflescope from dust, dirt, moisture and scratches while providing immediate access whenever you're ready to shoot.
Its proven Flip Open® spring-loaded mechanism opens instantly with a simple thumb press and folds completely out of the sight picture. The quiet hinge design ensures unobstructed aiming, making it ideal for hunting, sport shooting, tactical applications and airsoft.
A flexible rubber collar provides a secure friction fit around the eyepiece while forming a weather-resistant seal against dust and moisture. Constructed from impact-resistant polymer, it offers long-lasting durability while remaining lightweight.
Size 13 Eye fits riflescope eyepieces with an outside diameter of approximately 39.9 mm (1.570 inches). Always measure the outside diameter of your optic before selecting the correct Butler Creek cover.
