G&G Cylinder Head

The double O-ring design creates a tighter, more secure seal within the cylinder. This minimizes air leakage during the compression cycle, which leads to more consistent muzzle velocity and improved overall efficiency.

While it is designed for G&G G2, G2H, and standard Version 2 gearboxes, internal tolerances can vary significantly between brands. It is intended as a direct factory replacement for G&G systems, so fitment in other brands may require minor modifications or shimming.

Aluminum alloy is significantly more durable and resistant to the repeated impact of the piston head. While it is heavier than polymer, the added strength is ideal for high-performance builds where you need the component to hold its shape under stress.

Yes, applying a light coat of silicone oil or grease to the O-rings before installation is essential. This ensures a smooth seal and prevents the rubber from drying out or tearing during the initial assembly.

Yes, the cylinder head ships with the double O-rings already seated. You should inspect them for any debris before installation, but they are ready to use right out of the package.
