KA p90 and thompson = v6?
 

are these guns using true V6 gearboxes? I'm seeing a bit of conflicting info.

One vendor description had the KAp90 with a quick spring change gearbox, and I've seen a replacement m1a1 replacement gearbox is using 8mm bearings and no motor cage. Is the motorcage on the thompson the same as the p90?

The motor cage is in a completely different angle on the Thompson, so I "think" its a different motorcage.

Gearbox itself "seems" to be identical but I'll let a gun doc confirm.

Same mechbox. Motor cage moves.

cool... be interested to know if an E1/KS p90 motorcage fits on that m1a1 gearbox... as it's somewhat tight and misaligned on my CA p90 gearbox.
