Kraken piston head
 

What piston head and clyinder with fit in a kraken ak47? thinking of upgrading mine. also anything else to put into it?

Ummm im assuming its a V2 Gearbox?... so any V2 Gearboc Piston head and Cylinder?...

v3 piston head

its actually ver.3 gearbox, so V3 Gearbox Piston head and Cylinder, i was thinking of some upgrades but the FPS is high on this gun so you don't really wanna mess with that, more just to make it more durable and maybe increase the ROF etc.

Yeah I just wanted to make it more durable. Not really looking for more power.

don't quote me or anything as I know very little about gearboxes, but i think changing the shims/shimming or something like that is supposed to make it tougher and able to withstand a higher ROF

heh, oops... never really liked the AK so never really looked at it... :)

Pistons, piston heads and cylinders are the same for V2 or V3 mechboxes.

So what should I go with. My gun is stock right now. Looking for more durablilty and keeping around the stock fps. Im still a noob at upgrading

If you're looking for durability, I would recommend you install metal bushings and reshim the gears. A new piston, piston head, and spring guide would probably be good additions too, although you'd go a long way to increase durability and reliability with just the shims and bushings.

Do you know of any place I can get metal bushings?

Ta-Da!
