I was just making a 44 magnum and i am now currently making the animations for it. I was looking through the animations i have to make and i came across first-person overlay. I dont know how to make those and i cant find any tutorials on google or anything.

Id appriciate it if anyone could help.

First person overlays are for when you move to the left, right, and the gun's recoil. I use CAD's overlay script in order to make overlays. You don't necessarily need the overlays in order to complete animations, but you can if you want.

I make my own, it's really not that hard. Here's a list of what each frame should be:
Frame 0 - Origin
Frame 1 - Move Forwards
Frame 2 - Move Backwards
Frame 3 - Move Right
Frame 4 - Move Left
Frame 5 - Look Left
Frame 6 - Look Right
Frame 7 - Look Up
Frame 8 - Look Down
Frame 9 - Fully Automatic Firing

Don't worry about frame 9, you only need that for automatic weapons like an Ma5C or SMG. Just leave it as the origin.

Thanks ODX. That really helped.
