Description
Thanks to the double o-ring design this cylinder head sits incredibly snug inside your cylinder. With the tapered inside face each shot will have a more consistent volume of air pressure behind it. Providing the rest of your gun is set up correct and using decent quality BBs you should see an improvement in your shot accuracy over time
Features:
- CNC machined improving air seal
- Smoothed edges for a snug fit
- Double o-ring for a tighter air seal against your cylinder
- Smooth polished inside finish
- Sorbothane padded to create a damping effect from your piston head slapping against it during firing
- Tapered to improve air flow and shot accuracy
- Anodised Orange finish
Package Includes:
- M4 Cylinder Head

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.
If you require help with fitting any parts feel free to get in touch with us via our Contact Us Page.
