Ok so, I'm having trouble pinning down the name of the interface pieces related to the current/total ammo display, the current weapon condition and the current weapon condition label (CND).

What I have found are the following:
HUDMainMenu\ActionPoints\meter
HUDMainMenu\ActionPoints\right_bracket
HUDMainMenu\ActionPoints\justify_right_text
(which are the action point meter, shared background with the ammo display and the AP label)
as well as:
HUDMainMenu\CNDArrows
HUDMainMenu\AmmoTypeLabel
which are the tiny weapon condition marks at 75% and the current ammo type (JHP, SPC, .223, etc.).

So I'm lacking the UI names for the ammo display (16/236, etc.), gun condition and the CND label. If anyone happens to know them, or even better, where I can find that information, that'd be super.

So after lots of testing, I suspect the ammo count label and CND label are both also named:
HUDMainMenu\ActionPoints\justify_right_text
and the gun condition meter is named:
HUDMainMenu\ActionPoints\meter

So the Get/SetUIFloat/String functions can only access the first they find with that name, so I can't access those three things via script.
