I’m thinking of buying a new scope for a brush gun for deer and looking at something like the Vortex Optics Strike Eagle 1-6 x 24 AR-BDC Reticle My main concerned are of course, I want a scope that doesn’t fog up and is quality enough to last for years of hard use. I've never owned a Vortex before but I hear good things about them. Before I pull the trigger (pun intended) I'd like to learn a little more... my questions. 1) does Vortex it fog up in cold rainy weather? How long does the "no fog" last? 2) quality of vortex? 3) Im still open to other brands, anything out there in this price range (or less) worth considering?
