This is a full metal rack, so your gears must be shimmed as close to perfection as possible.

An excellent piston to modify too, swiss cheesing and modifying the rack is often seen when correcting your angle of engagement.

  • 2nd tooth has not been removed (may need to do this depending on your angle of engagement)
  • Suitable as a piston ot modify such as swiss cheesing
  • Webbed bottom surface to improve strength over standard pistons

Special Instructions:

Should you need to remove the 2nd tooth of this piston (fist after pickup), remove the rack first. Once you have done any kind of modifications to the piston, we advise you glue the piston rack back in place.

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.
