A replacement cylinder head for various gearboxes. Double O Ring construction and a crying shame that something so beautiful has to be hidden away!

Just what I needed

Used this to replace the stock CA cylinder head. This is far superior in build quality, the steel construction is better able to take the pounding my M110 spring gave it and the double O ring seal ensures no air goes to waste.
Important Information


All images, product contents and specifications listed are based on checks performed when a product is first listed and may differ due to changes over time made by the manufacturer. This includes package contents in regards to any 'extras' provided e.g. Sample BBs.

Items used in images to promote the main item (Holsters, Camo, etc) are not supplied unless listed in the Specification tab under 'Extras'. This includes attached rails, grips, scopes, suppressors etc.

Chinese supplied Batteries and Chargers are warrantied to be not DOA (Dead on Arrival) only. We always recommend swapping out to a better quality Battery and Charger at the earliest opportunity.

Custom Painted products (Two-Tone) are non-refundable as these are painted to order. 

Unless otherwise stated, all products are sold singly.



Any figures used are based on tests performed on the products when they are first listed. These can vary due to changes by the manufacturer, gas pressure, gas used and a number of other factors. All figures should be treated as an approximate guide and used for reference only. 

All listed FPS are +/- 5% due to differences from rifle to rifle. If you require a guaranteed FPS, please add an upgrade/downgrade option on to your product (this may cost extra).

No airsoft AEG is warrantied for use with an 11.1v LiPo or higher voltage battery at UK velocities (373fps or lower) unless specifically recommended on the product itself. Use of higher voltage batteries can cause failures and will negate any warranty implied or otherwise.



We cannot offer an exchange on pyrotechnic devices due to device failure. We are unable to guarantee that the pyrotechnic device has been stored in a moisture free environment or used correctly in accordance with the manufacturers guidelines.
