Different system yes, but the mod is exactly the same.

All your looking to do is make the floating valve sit further back in the nozzle, that is achieved in exactly the same way as you would for a WE open bolt gun, trim off the prongs that the floating valve sits on, drop it all back together and see what FPS your running, then you know how much more (if any) you have to trim to get the FPS your after.

I'd bet my MP5k that's all your paying to have done.
