KAC PDW upgrade suggestions?

Recommended Posts

Hi i've got a Dboys KAC PDW (all stock parts)

 

i'm looking to hopefully upgrade it to make it more efficient i suppose; any ideas what parts to get? i'm looking maybe to make the FPS more consistent to 330-350, and increase ROF.

Well, if you want more power, an M110 spring; that knocks the FPS around 330 - 350, but upgrading power doesn't always do the job, It puts more strain on the gearbox itself, the trusty M100 spring always works perfectly.

 

Also, lowering fps to around 280-300 will only increase the ROF since it takes less effort for the motor to turn the gears.

 

If you want a higher fire rate, first of all, change the battery to a 9.6v if you haven't done so. Then you should grease your gears and bushings a bit more to decrease friction. The fastest fire rate I would recommend would be be around 900-1000 rpm. Anything faster, you will run a risk of wearing down the gearbox or motor faster than you'd expect.
