Full description


This CNC alloy piston head produces a great air seal when combined with the right components. Secured from the inside of the piston, you will need a long handled screw driver to aid assembly and we also recommend a small drop of thread lock to prolong the life and durability of your AEG internals. This piston head will fit into 99% of Airsoft AEG's out there no matter what gearbox version you are using. The front face also has 8 ports to properly inflate the thick o-ring for an improved air seal. Included is a bearing system too that when under load keeps your main power spring compressed straight. This improves your shot for shot power consistency massively.


  • Solid CNC alloy construction
  • Bearing braced spring support to keep your power consistent and spring straight
  • 8 port ventilation to properly seal your piston head inside your cylinder for incredible an air seal
  • Quite a thick o-ring to improve your air seal
  • Secures onto your piston from the inside using an included heavy duty screw

Parts Fitting

Upgrades and Downgrades should only be undertaken by experienced players, or Airsoft Technicians. Please note, changing any internal parts of a weapon voids its warranty unless done in-house by our staff. 

Please ensure that when fitting parts the part purchased is the correct part, as once a part has been fitted we cannot accept return.

We do know that players love to tinker, so we're here to give you help should you require it, and if needed you can get in touch with our workshop for more help!

Unique Parts

Please note that some parts may be unique to a specific brand of weapon. For example: Parts for an ASG M4A1 may not fit an ICS M4A1.

Parts from the same brand typically have a high chance of fitting, though be warned, some replicas use unique parts, so please ensure the part will fit before you attempt to fit it.
