Overview:
Three .50 cal Brownings, made to be somewhat size and weight accurate. Fires M20 API-T rounds.
The three guns are: GAU-21/M3 (yellow), AN/M2 light barrel (olive drab), and M2HB (Brown). Their cyclic rates are 1200, 750, and 600 rpm, respectively.

Installation:
Grab by the receiver assembly (the jet-black structural panel, painted red in this picture for highlighting), and mount it on pretty much anywhere that's not a wing surface.

Background:
Yes, I have posted the original (which I have deleted, no need for it to clog up my inventory anymore) nearly two years ago, but I felt there's still something missing: how do I make the smoke (and casing ejection) effects look more realistic? Would particle effects cause issues with the predictor? Now, I've got the answer here, and with it, my third attempt to make our beloved Ma Deuce even more realistic. Gone are the smoke trails that follow the bullets: now smoke is smoke and they would trail behind the "aircraft" guns... or stay in front of the (normally land-based) M2HB for a fraction of a second before dissipating.
I have also made them sound realistic as well: from the dull thumping of the slow-firing M2HB, all the way to the rapid "pop"s of the AN/M3, now when these weapons fire they should sound distinctive... and sort of War Thunder-ish.

Note:
All weapons are (sort of) synchronized. Because guns on WWII aircrafts IRL would fire in salvos regardless whether they use synchronizers or not. That's just how those wires and solenoids work.
