M16+m203 w_model rigging

Hi. I’ve already made several attempts at rigging this w_model for npcs to hold correctly in the RPG stance (its a better looking stance for this weapon, imo). I can’t quite get it to work correctly in GMod so I’ve come here hoping for some help. Thanks for your effort and time!
The models + materials come from the Full Life weapons pack. I’ll upload the necessary files…
