I'm also cross eye dominant but I still shoot with my strong side, it doesn't affect me really.
I also sometimes run an aimpoint m4 when I use a magnifier because I don't like the way the EO Techs get fuzzy when magnified. Plus it's got a 2 moa dot so it doesn't blow up on you when magnified. Solid optic IMO.
I'm not overpaying for anything, I have been pretty patient with everything except ammo. But I didnt have anything before this started, and I will be damned if something passes and I dont have the chance to ever own any of this stuff
