glare on eyepiece ruining my sight picture

use a sun shade

Callbarry, no caps ,to start your sentance ,no period ,to finish with.,Im disapointed.

im just kidding with you.

get a slip on rubber eyecup.

OH! Geez! The eye shade pictured above is made by UTG. You can spend your monies if you want, but this "thing" is so stiff, it is unusable! They (UTG) sent me another one, and it was worse! 

The only one I have used that is worth its salt, is the latex one which comes with the ATN series. Too bad it isn't adaptable to others.

One way around the issue is to buy a hat with a very wide brim. I found mine at Big 5. It has a 6 inch brim, and cost just $20.

Change your shooting position. Not joking. I have similar issue but moved slightly to one side a few inches and tree blocks sun now.
