SHS damping cylinder head and piston head, Ver.3

SHS silencing aluminum cylinder head and piston head version 3 for gearboxes. Suitable for, among others, AK series electric airsoft guns. The cylinder head also has a double seal to improve tightness. The end that comes inside the cylinder has a conical cushion plate and thus the cylinder head works excellently with the included silencing, so-called "silenced" / "damper" piston head. Dampens sound and reduces the stress transmitted to the box, improving the durability of the gearbox.
