How do i make the mag of this gun drop out? Please help me?

I am trying to make this gun magazine drop out when reloading. sense i have no clue on how to do that i am trying to model off of other scripts, now that is not working out correctly, that left me only one option that is to ask for help.

This script is not mine but i am trying to model off of scripts like this to make my own. its is very long i really would appreciate this, if it works i will make give the person the model i had to trim the script becuase of its lenth.
