this piston is amazing! i have a kwa gun and all i hear is good things about this piston. I contacted kwausa and they say their pistons are made of not polycarbonate but fiber reinforced ballistic polymer! asgi tested this piston in a kwa with a 16v lipo battery and the gun endured through 8 hi-caps! Asgi also tested a highly upgraded p90. the Prometheus hard piston inside the p90 didn't last one shot before the back of it was torn off from the intense speed of the gears. If it can stand over 2000 times longer than a Prometheus hard piston its pretty good in my eyes.
fiber reinforced ballistic polymer!
aluminum piston head
reinforced on the last 4 teeth
good deal for getting an amazing piston and a piston head
12000+ shots on it so far and still sounds healthy as when i got it
definitely buy it if you want a reliable gun!!!
