V2/V3 SILENT CYLINDER HEAD, EXTRA SEAL [CYMA]

The CYMA V2/V3 Silent Cylinder Head with Extra Seal is a small but very effective internal upgrade part designed to improve compression and reduce noise in AEG gearboxes. Made from CNC-machined aluminum with rubber sealing elements, it feels solid and well-finished, offering a noticeable step up in quality compared to many stock cylinder heads.

In terms of performance, its main advantage is the improved air seal thanks to the reinforced O-ring design. This helps achieve more stable FPS output and better overall consistency during firing. It also contributes to slightly quieter gearbox operation by reducing piston impact noise when paired with a compatible silent piston head.

Installation is straightforward for users familiar with gearbox work, though as with most internal upgrades, proper fitting and lubrication are important for best results. It works well in both V2 and V3 setups, but optimal performance depends on the rest of the compression system being properly tuned.

Overall, this CYMA cylinder head is a reliable budget-friendly upgrade that improves air seal efficiency, consistency, and durability without unnecessary complexity.

Not much to say about this part. It's a great upgrade. With this piston head and cylinder head combo you eliminate the "slap" sound when the gearbox is cycling part; good build quality, great seal with the cylinder. Make sure that you use it with a silent/mushroom piston head for the optimal performance.

I believe these are the same cylinder heads put into the plat line of cyma replicas,do be sure to pair these with a o ring nozzle and a good piston and cylinder set to get the max fps performance and best performance overall.

A very nice cylinder head. It's made out of metal and it seals very well. Also, this head is a bit longer then stock cylinder heads - it goes deeper in the cylinder. That will help with correcting AOE (angle of engagement) - when the gearbox needs it.

It's a good cylinder head.

I had no airseal issues after installing it (Army Armament AUG).

I believe it to be the same one, as in the CYMA BLUE guns (so a good one), just in a different colour. I compared them next to eachother and they seem to be basically the same.

It doesn't make your gun super quiet, but a difference in noise is absolutely noticable.
