I have a problem, I am looking for a good scope cap, or some way of keeping the rain and snow off the inside of the scope. I see alot of caps that you have to push a button to have them open, also the ones that you flip off, I use the ones that keep the snow and rain off the inside but they always fog up, or rain droplets on them, They work for sh-t when you have to pull up and shoot fast, you cant see. I was thinking about trying to put some rain-ex on the scope and trying that. Any suggestions would be appreciated
