Vortex Defender Flip Cap Eyepiece (40-46mm) E-10

In the heat of a hunt or the intensity of a competition, your gear shouldn't be a distraction. The Vortex Defender Flip Cap Eyepiece (40-46mm) E-10 is the rugged, reliable solution to the flimsy plastic caps that often fail when you need them most. As a premier Vortex Defender flip cap, it features a high-tension spring that snaps open and stays out of your way. Whether you're trekking through a dusty basin or waiting out a rainstorm in a treestand, this scope cap keeps your glass pristine until you're ready to take the shot.

Vortex designed these scope lens caps to be as versatile as their optics. The E-10 model features a flexible sleeve that creates a snug, weather-tight fit on eyepiece diameters ranging from 40mm to 46mm. Unlike standard Vortex scope caps, the Defender series offers a unique three-stop position: flip it to 45 or 90 degrees to read your ballistic data (often taped inside the cap), or push it back to 180 degrees to lay flat against the scope body. This is a Scope Accessory built by shooters, for shooters, ensuring nothing stands between you and a clear image.

The Vortex Defender flip cap is more than just a cover; it’s a bodyguard for your riflescope’s ocular lens. While it fits almost every Vortex riflescope, please note it is not compatible with the 1-inch tube Viper® models VPR-M-01BDC, VPR-M-04BDC, and VPR-M-03BDC. At EuroOptic, we know that reliability is non-negotiable. Backed by the legendary VIP Lifetime Warranty, the E-10 is a simple, effective upgrade that protects your investment and enhances your shooting experience.
