Magnetic Compass for PVS7/14/15s

I managed to pickup one of those magnetic compasses that goes on the front objective (NSN 5855013816052) and Im having an issue where when the unit is mounted I cant see the compass because it is sitting to far off the edge of the front objective. Are there different models of this thing, one that was for PVS7s, 14s, etc... or am I not putting it on right?

Nope, they are just sorta garbage. 95% of them (IME) have a loose prism, and you need to re-attach it at the right angle. I bet that's your issue. Try poking it back into place (it'll stay if gently handled for a bit) and mounting it up.

Be happy the switch works. Many of them have too much glue, are locked up.

Also: test it every time. Every time. I kept the best of a large set when I fixed a bunch up and one day when doing PCI it was 30° off. Forever. Broken. How? No idea.
