Action Army Aluminium Cylinder Head Ver III

The Action Army Aluminium Cylinder Head Ver III features a double O-Ring for a better air seal when attached to the cylinder.

The cylinder head also has a rubber pad that dampens sound when the piston head comes into contact with the cylinder head. A better air seal due to the double o-rings, for example, ensures a stable Joule/fps value.

This cylinder head is only suitable for a V3 Gearbox!
