Vortex Defender E-10 Eyepiece Cover

This is the last flip cap you will ever need!
Virtually indestructible, this cap will fit snugly on nearly all Vortex
Optics and features a snap flat spring that will keep your line of sight
unobstructed.

Rifle ranges the world over are littered with broken flip caps. This
is one cap you will most likely never see in a flip cap boneyard. The
E-10 cap has three stop positions. The first vertical, to put your dope
disk (optional accessory) literally right in your face. The second at a
45° and the third at 90° to lay flat back.

The E-10 fits all Vortex® Riflescopes except the 1-inch tube
Viper® model VPR-M-01BDC, VPR-M-04BDC and VPR-M-03BDC. Outside diameter:
41.5-46 mm | 1.6-1.8 inches
