How to put a CETME C stock on your PTR receiver

Couldnt find a good video on this so i made my own.
If you look around online youll see tons of people talking about this but no good pictures or videos.
This is how you fit the factory cetme c stock on your ptr receiver with minimal modification.
This should work on any of those hk roller delayed style receivers but i am specifically using a ptr91 receiver.
