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

Versatile Flip Cap for Vortex Riflescopes

The Vortex Defender E-10 eyepiece flip cap fits 40 to 46 mm oculars on most Vortex riflescopes. It excludes the 1-inch tube Viper models VPR-M-01BDC, VPR-M-04BDC and VPR-M-03BDC. The stainless steel spring holds the lid at vertical, 45-degree and 90-degree stops. A vertical position allows a dope disk to be inserted for quick reference while shooting.

Stainless Steel Build with Multi-Stop Hinge

Constructed from stainless steel, the cap weighs 1.6 ounces and is described as virtually indestructible. The hinge mechanism locks securely in three positions so the cover stays out of the sight picture or folds flat against the scope body. No battery is required and the unit mounts on standard Picatinny or Weaver rails. The package measures 8.15 by 3.62 by 3.58 inches and weighs 0.18 kilograms.

Replaces Standard Plastic Caps for Heavy Use

This accessory upgrades from basic tethered plastic caps that crack or lose tension after repeated field use. The metal spring and positive detents survive hard knocks, mud and temperature swings without loosening. Hunters who flip the cap dozens of times per outing will appreciate the consistent action. Buyers needing a larger objective cover should note the matching O-24 24 mm objective cap is sold as a separate item.
