When trying to co-witness my irons with my zeroed in red dot I have to move the rear sight pretty far to the right. I'm guessing if everything is aligned correctly they should lineup fairly centered or is that an incorrect assumption? the front sight is mounted on a railed gas block and the rear sight is a magpul flipup.

Yep, they should line up straight. Something somewhere is cocked, probably the gas block. I'm assuming that the red dot is centered on the rail.

I'm about 100 mile south of you, down 67

It is not an incorrect assumption. Our anatomical structures, in this case our face will be different for everyone as long as your picture sight alignment is zeroed to you and when using your iron sights this is what your sight alignment looks like.

Thanks for the replies. I need to double check the gas block.

No doubt on that, we actually moved down here from Festus and it was bad enough. I used to go pick up my aluminum bar stock up there off Goodfellow at Shapiro's. Always had the old 12guage riding sidesaddle, and that was before Ferguson.

with iron sights there is no parallax. with red dots vs distance, you may have some. there are red dots that are made to not be a problem from 100 yds out. look thru red dot at target and move head up dwn and see if dot moves. if so, thats parallax. now look at target at 100 feet and it won't move.
