Thanks a lot gentlemen, I really appreciate the wilingness to help.
Yes, I'm shooting with both eyes open, closing
second eye works just fine.
Closing front cover also works, it's a pretty good compromize actually.
No, I don't have Duane's syndrome, I tried with my head square to the target, doesn't seem to
be any different.
Yes, I'm focusing on the target only, never on the sight. Were I to shift my focus to the red dot, I would see irregularly shaped red blot about 30 MOA in size intead of a 4 MOA dot.
Actually, my vision in both eyes is excellent,
in a group of shooters approaching to check targets on the range I'm usually the first one to see bullet holes in the white from the distance.
I guess I'm in some minority wired differently,
my hands are also ambidextrous, I use tools better with my left hand, I write and use utensils with my right hand. I shoot AK on the left and FAL on the right.
Thanks again.
