Gun model not corectly pointing at center of screen when using ironsights,Gun model not correctly pointing at the middle of the screen when aiming

I made a Gun Model for an MP40, now when I aim it using the animator, and I look around, the Ironsight doesnt correctly follow the Crosshair im Using, only when aiming straight forward, up, or down! I tried putting the weapon in a new position, but that didnt work either, I would appreciate some help, and thanks in advance!

Heres my Scipt for Automatic Weapons, and Pictures of what I mean, if thats of any use...
