I think we need some kind of indicator for when your bipod is deployed because it is not obvious in either automatic or manual deploy.

Prone Manual issue: If you're prone and moving, sometimes it will stay deployed and other times it will secretly fold up, so when you start shooting the m249 you have no idea what to expect.

Standing/crouching: similar issue where it's difficult to tell if you're deployed properly, but additionally you're pretty limited on the places you're allowed to deploy.
