ASG Ball Bearing Polycarb Silent Mushroom Piston Head for Airsoft AEG
Materials: Polycarbonate Inner, Aluminum Surround
Compatibility: All Marui compatible Airsoft AEG that uses standard piston heads. (Ver.2,3,4,5,6 and compatible.)
The polycarbonated piston head is equipped with built-in pressure bearings to reduce friction from the spring. The piston head is ventilated where holes in the piston heads ensure that the rubber seals are pressed against the cylinder when the air is compressed. This gives optimal compression of hte air seal and minimizes wear and tear on the rubber seal. The mushroom head piston head also provides a stealth gearbox operation where the aluminum piston head will create a sharp snap sound when fired.
