SHS damping cylinder head and piston head, Ver.2

SHS silencing aluminum cylinder head and piston head version 2 for gearboxes. Suitable for, among others, M4/M16 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. The combined effect also reduces the stress transmitted to the box, improving durability.
