Quick question guys. Feel free to tell me to GTFO.
I notice a lot of you blokes have your backup iron sights mounted behind the optics, the ones that don't flip down. I don't have any experience with anything but iron sights, I was just wondering how the sight picture is, when looking through the rear iron sight into the optic.
I'm guessing it's done in case you smash your Aimpoint etc. on a rock or something?
