Sights acting weird.

It would be close if not right on if the iron sights weren’t jacked up and zeroing to the extreme left or right.

That comment and the comments about co-witnessing have confused me. If an optic is parallax free, and most red dot type sights are, or very close, then if sighted at the same distance shouldn’t they co-witness, even if no attempt was made to co-witness?

Yes, one can’t have 2 points of aim with a single point of impact. That would mean at least one of them were off (if not both).

Ime, the aperature skews the dot and the optic skews the post, especially with non absolute cowitness setups.
