Aluminum cylinder head with ball bearing from G&G Armament is suitable for V2 gearboxes. The Reinforced version is equipped with 8 air intake holes that press the strong O-ring against the cylinder, ensuring a high level of tightness. The cylinder head is a bit louder when shooting due to the material, but also a lot more stable compared to the polycarbonate piston heads. The included ball bearing prevents jamming or misalignment when shooting.

According to the manufacturer, the Piston Head is also ideal for heavy tuning.
