My rear peep sight on my Norc M4 is adjusted almost all the way to the left. I was wondering if my front sight could be out of wac. It looks like it's in the middle but what is the adjustment procedure with those.
 
Nothing is wrong as long as you can achieve zero, everybody's cheek bone structure and eyes are set apart differently, to get a proper cheek weld the windage adjustment will be different for everyone.

I've never even thought about this. Does this mean that if someone else, say with really big cheekbones, shoots my rifle, their point of impact will be different? :confused: Seriously, I'm not being sarcastic.
 
Not sure about the cheek weld thing. The position of the rear aperture relative to the front relative to the barrel determines POI. I've heard of this with scopes but I think this has more to due with parallax. There is no parallax error with iron sights. Of course I could be completely wrong.

As far as the front sight, there is not windage adjustment here, only vertical for zeroing against the rear sight to get the correct elevation at a given range for a given rear sight elevation setting.

I don't know about that. The sights line up with your eye, not your cheek weld.
 
My Stag rear aperature looked like this [....O..]
My Norinco looks like this [.....O.]

I don't think that it has anything to do with cheek weld. Just tolerances stacking up.

I should think so long as you've got a hand-full of clicks (maybe 8 or so) you'd still be in spec.

Can anyone else chime in on this?

It does kinda drive me nuts tho, it is not aesthetically pleasing.
 
My new CQA has the front sight a little to the right and the backsight came adjusted 2/3 of the way to the right as well. Still haven't shot it yet.

All of this can be seen in the Strikefire red dot I have mpunted on it.

How hard is it to knock out the tapered pins holding the front sight in place so that I can rotate it to vertical? I read in another post that they are a bear to get out. I have a vice and brass punches.
 
Do you guys gets unwanted windage shifts between small and big appertures?

I definitively get this with my Norc and it seems I got problem too with the TechSignts on my 10/22 but didn't test it too much.

I noticed this also.
When I use my small aperture sight my grouping's were similar to my groupings with my optic. So this lead me to believe that when I was using my large aperture rear sight not correctly when shooting with it. Although I do not have a Norinco AR15 so I can not confirm or deny that it could be the same issue's that M14 people have with there rear sight's being wanky too.
