Unknown jam, and the revsolves
 

TSD/SRC gun jam what it looks like.

Upon doing some last minute dial in with my red dot on a TSD/SRC M4A1 I heard a click then upon next trigger pull the "whirl of death" ... oh crap

The Bits are the gear hope you can see this in the pics

Lesson learned "stay with high quaity BB's"

BB's would not cause this.

Oh they did there was 3 jammed in the barrel... Upon the tear down I found out

Still, that would not be the cause of your gears stripping. That's just not how it works, not possible.
Also, is the bottom axle on your bevel (motor-contacting) gear missing/broken? It looks like it. That could be the cause of your stripped gears

yeah .. the clink was the bevel gear shaft letting go and going cock eyed, and then the carnage in your picture.

All shafts were intact, none broken
The gearbox was never taken apart before, also the piston is striped as well. Just a bad box from the factory I'm thinking ....
