Vortex Flip-Up Scope Caps with Dope Disk

We’ve used these Defender Flip Caps on varmint rifles and they work great — and having your ballistics dope inside the flip cap is brilliant. The E-10 eyepiece Flip Cap is “stretchable” to fit eyepieces with outer diameters of 40-46 mm (1.57-1.81″)*. The caps for the front objective come in a variety of sizes from 24mm to 56mm. The spring-loaded E10 eyepiece cap offers three stop positions: The first is the vertical position, which will put your optional dope disk “front and center” for easy viewing. The second position is 45° back from vertical and the third is at 90° from vertical, laying flat back.

Introduced last year, the Vortex Defender Flip Cap is already a “best seller” on Amazon.com. Most purchasers have been quite happy with this product, which have proven very durable. Here is a typical review: “I’ve used scope caps from different manufacturers but these are by far the best! The fact that they can be stretched to fit eyepieces of varying size puts them over the top. Besides the fact that they are indestructible.”

Make Your Own Custom Dope Disk
Vortex Dope Disks cost $9.99. These are truly “custom” — you enter your own ballistics data on the Vortex Website to create an insert that fits inside a Vortex E-10 eyepiece flip cap. Disks are made from a durable plastic, custom laser-engraved with user-specific ballistics data. Choose single-column, two-column, or reticle-style display (shown above), and select the font size (big fonts help older eyes). CLICK HERE for Dope Disk Data Entry Page.

*Note: The E-10 eyepiece cap sleeve may cover the in/out eyepiece focus adjustment on some scopes, so you should set that adjustment before installing the cap.
