I actually haven't tried a red dot. I think I do have a minor astigmatism. I have a spitfire prism that works well but I want something more durable or reliable. I'll look into your suggestion. It looks nice, how's the window size? Do you feel like there are blind spots?
If you have astigmatism, like I do, a red dot may not work perfectly for you - have you tried any yet?
Even with my wonky eyes the true holographic sights are fine. I have a QD swing out magnifier behind mine so I can cover multiple roles.
