Actually no it isn't. The G10 we had ingame back about 05 or so used the same FM as the present K4.
The real G10 would be about 20 to 25 mph slower and IIRC has a slightly lower FTH.
I would like to see a G10 added but not before we get AS versions of both the G6 and G14. The G10 entered service after the K4 so it wouldn't be all that useful for events,except to give a 20mm option.
Guess I should have read Karnak's post...... just ignore my ramblings...
