Systema Revolution. Anyone familiar? Compatible pistons?

I've been running this thing for a few years...or rather HAD been, until I stopped playing a couple years ago. Had it open a couple times to clean and grease it...I've tried to keep my use to semi auto because of its age and perceived scarcity of replacement parts(and semi with this thing is pretty awesome anyway)...but a friend ran it on full auto, got a bb jam and destroyed the piston...
Anyway, everything else looks great in there, the piston seems to be standard V2 diameter and length, but the head looks different. I've never had that thing apart, and don't know how to get the head off to swap the parts onto another piston...can I even?
my google skills can't find me the answer and I hope someone here knows a little something on the topic, as my fiance isn't gonna let me off with spending much money on airsoft atm...
Thanks in advance!

Looking at web pictures, it looks to be a regular ptw style piston & piston head. If that is the case, and the piston head is ok, any ptw piston (or a we katana “upgrade” full stroke) will work

what a stupid fad those things were lol

It's a ptw piston head and probably a regular ptw piston as well
$100usd to replace if they're both PTW parts, which they probably are

There's lots of aftermarket PTW cylinders these days. You could try a real cheap one.

Alternatively, if the piston head itself and piston are fine and the rack gear is just destroyed you can buy those alone for much less. You have to cut one side of the plastic along the side that holds the gear in to get it out then superglue the new rack gear in but I've run PTW cylinders with M130s in like that after my PTW ate a couple rack gears.
