About the Vortex Defender Objective 50 Flip Cap
The Vortex Defender O-50 is a tough, snap-open flip cap for the objective (front) lens of your optic. It fits optics with an outside diameter of 55-59 mm (2.2-2.3 in.), and its spring flips the lid fully flat so it stays out of your line of sight. Rubber-sleeved fit means no tape or shims.
Key Features
- Nearly indestructible – built to take bumps, drops and cold weather
- Snap-flat spring – lid opens fully and stays clear of your view
