IIRC, the aircraft version of the M2 had a higher cyclic rate than the ground pounder version.

Oh yes, it did fire a lot faster. When one of us fired, there was no intercom possible on the aircraft.

Just dug out the Dec 2016 AR to read again what they had to say about the aerial version. They made it sound like it was more than just a barrel change. Had something about .30 cal guns like that as well.
