M4A1 details.

I have noticed two important things on the M4A1 that could definitely use an update. 

1. The selector doesn’t flip to full auto, when using full auto. It is consistently on semi-auto regardless of the firing mode. 
   
   
2. Fully depleting all your ammo should mean that when you look into the chamber with the firing bolt retracted the ground should be visible through the well, or an empty magazine should be visible. 

Hope this is insightful/helpful to your team.
