"It is an ok piston it's nice if you use the steel sear. Your stock piston will get a better airseal though. If you want an upgraded piston for the a&k,matrix, or ka spring svd go to airsoftpro there the ones who originally made the parts pps and the others just do cheap knock offs that unfortunately don't work quite the way they should.
