Butler Creek Flip-Open Objective Lens Cover 51.9 mm

Flip-open scope covers for the eyepiece and objective lens of rifle scopes are a modern solution that effectively protects hunting optics from scratching, getting wet, dust, and impacts. The flip-open cover is locked and opened with just one finger, making it practical to use.

The opening lever is very quiet; it's the quietest flip-open cover on the market! Additionally, it is waterproof and does not become brittle at low temperatures (made from flexible ABS polymer material).
