Cylinder head Mk.II for AEG, V2/V3, extra long - No Pad

The AEG Mk.II cylinder head for V2 / V2.5 / V3 gearboxes is a well-engineered upgrade part for users who want to improve air seal, performance consistency, and feeding reliability in their AEG setup. Thanks to its unique design, it provides a firm fit inside the gearbox without unwanted movement, helping reduce power loss, improve shot-to-shot consistency, and lower internal wear.

One of the main advantages of this cylinder head is its increased tappet plate lift, which allows the use of a nozzle up to 1 mm longer compared to standard designs. This helps achieve a better seal between the nozzle and the hop-up bucking while maintaining reliable feeding. The result is more stable performance without having to compromise between sealing and proper function.

The body is made from EN AW 7075-T6 aerospace aluminum and features H+PTFE surface treatment, ensuring very smooth nozzle movement, high wear resistance, and long service life. The design is intended as a universal solution for gearboxes from various manufacturers, and the locking pin holes are also optimized for Retro Arms gearboxes.

This product is available in multiple versions under the Variant parameter, which distinguishes nozzle length and impact pad configuration. Versions with an impact pad use durable PU rubber for better piston impact absorption, while the no impact pad versions are suitable for users who want to install their own PU pad or Sorbopad and fine-tune the setup individually.

Variant:

• Extra Long / 70 sh
• Short Nozzle / No Impact Pad
• Extra Long / No Impact Pad

This cylinder head is a great choice for anyone looking to get better reliability, improved air seal, and more stable performance from their internal setup.
