CNC Piston head with the bearing

Aluminum piston head with counterpressure function and bearing, designed for upgrading airsoft guns. Thanks to CNC machining, it offers precise dimensions and higher durability compared to standard plastic parts (12 g).

Counterpressure system: The front of the head contains six air channels. When moving forward, air is forced through these channels under the O-ring, which expands under pressure. This ensures a better seal in the cylinder than with conventional heads.

Ball bearing: The head includes a bearing that allows the spring to rotate freely around its axis when compressed. This reduces the internal tension of the spring and facilitates its operation.
