Kns precision adjustable gas piston system - KNS Precision Adjustable Gas Piston System

Great piston. Does exactly what it says it does. All metal construction and solid. Installation to screw it in and tap the roll pin in, took all but 1 min. It’s the removal of the old piston and thread clean up that is the pain and time consuming part. My WASR piston was welded on. Anyway set up is easy. Just follow some YT videos which 30 clicks open is around the magic number. Mine cycled just fine at 33 clicks open. I settled on 32 for the sake of reliable cycling. My casing now land about 5 feet away as opposed to 20-30 feet away. Great mod for any AK that is over gassed or if you run suppressed.
