AS 42 sound: inside\outside

AS 42 have louder gunfire sound than outside. Meanwhile, this is open-top car. This do-do-do-do-dom sound and fully open space around character makes dissonance. When I’m leaving car, standing nearby and listening my AIs fire at enemy, the sound is much quiter. The only I can suggest is just make MGs inside sound like outside (but maybe that would be better than it is now).
