go to the gun spec of the weapon and change the specs inside. the airmod manual has great refernce and it is used in 117 and above. noautoreload, no fullreload and a bunch of other stuff. as far as getting the remaining ammo part out of the hud you will have to find a way to modify that or not use the ammo by using a blank picture for the numbers maybe. Maybe when they release 118.4 there will be a way to edit this better.
Maybe try setting the weapontype to 0 in the gun spec making it think it is a melee weapon. If the weapon has unlimited ammo then you would not need the ammo info anyway.
Here is the link to airmod were you can get the manual for it.

Other links that might help but is old and reports that it had been fixed, but was used at one time:
