All rights to this unique content are tied to the anareus.cz domain.The RetroArms CNC POM X piston head is designed for building and upgrading the compression system of electric AEG airsoft guns. The body is made from durable POM using precision CNC machining, combining low weight with accurate dimensions. The lower weight is particularly beneficial when you want to avoid unnecessarily increasing the mass of the moving piston assembly. The characteristic X-type design is engineered with airflow in mind and uses two O-rings for reliable sealing inside the cylinder. A properly assembled and sealed compression system reduces unwanted air loss and helps maintain consistent AEG operation. The POM version is a suitable alternative to aluminium piston heads, especially for builds where low weight, durable material and precise CNC machining are priorities.
The polymer construction made from POM offers low weight and good mechanical durability, avoiding unnecessary additional mass in the moving piston assembly.
The piston head is manufactured using CNC machining, allowing precise dimensions that are important for proper compression system operation.
The specific X-type design is engineered for efficient airflow as the piston head moves inside the cylinder.
The design uses two O-rings for reliable sealing, helping to reduce unwanted air loss inside the cylinder.
Suitable for building, servicing and upgrading AEG compression systems when you need a lightweight POM piston head with precise CNC machining.
The main advantage of the POM version is its lower weight, so it does not unnecessarily increase the mass of the moving piston assembly. An aluminium version, on the other hand, makes sense where a metal construction is preferred.
The two O-rings are part of the piston head design and help provide a reliable seal inside the cylinder. This reduces unwanted air loss during firing.
The X designation refers to the specific shape of the piston head, designed with airflow and proper sealing performance in mind.
It is designed for AEG compression systems, but dimensional compatibility and proper operation with the specific cylinder, piston and other components of the build should always be checked before upgrading.
