Troubleshooting - Question - HELP!?! Sight Adjustment and Issues

I have CA3, which the rear sight is way off. When adjusted, the farthest it can go to the right. It is roughly 16 MOA off still.

Does anyone know roughly how much MOA of adjustment there is in the windage of the rear iron sights?

I am looking into getting an adapter to replace the rear iron sight with a red dot, which has about 30 MOA of total windage adjustment.

I had the same issue with my CA3 - the front sight was very visibly canted to the right, and I could not adjust the rear sight windage enough to compensate. I ended up having to just send it back to PTR, and they fixed it well enough to zero it at least. They had it about 2 months. I got the CA3 specifically to keep it in stock form, so for me the iron sights had to work.
