got my new vortex strike fire today. only 2 days after ordering it and the shipping was free. So i decided to mount it up since my yhm backup iron sights wont be here til tomorrow. My question is did I mount it too far forward? I kinda feel like there wont be enough room for the flup rear sight if I dont mount it so far forward. This setup is for absolute cowitness but does that mean I should use the rear sight too. Or is the cowitness with the front sight only? btw this thing seems really well built and seems so far like a pretty good optic for the money.
