This is the aluminum piston head made by Super Shooter. It has a ball bearing and is well vented. The head is secured with a machine screw with a lock washer. the face is perfectly flat except for the slight bevels around the vents. The bevels should protect any sorbo installed on the cylinder head from damage. Please note this head is much heavier than plastic heads which can increase FPS and is good for heavy BB weights but can reduce ROF and put more stress on the gearbox shell. Note: Piston heads have a tendency to sometimes unthread themselves in high speed conditions. The solution to this is NOT to tighten the screws as tight as you can, the solution is thread locker. That is why they make it. Overtightiening can reduce the life of any piston head as it can weaken the threads.
