Guarder AEG Bore-Up Polycarbonate Piston Head (GG08-09)

The Guarder AEG Bore-Up Polycarbonate Piston Head offers increased air volume for higher performance, improved air seal, and quieter operation due to its lightweight design. Its polycarbonate construction is durable, and the bearing system reduces friction and spring tension, while the six-hole ventilation enhances stability during automatic fire. This part is designed for "bore-up" cylinders and must be used with other compatible bore-up internal parts. 

Benefits

• Increased air volume: The "bore-up" design features a larger inner diameter, which increases the amount of air compressed with each shot, leading to higher performance and FPS (feet per second).

• Enhanced air seal: The silicone O-ring provides a better seal against the cylinder walls for more efficient compression.

• Quieter operation: The polycarbonate material and specific ventilation holes help create a quieter shooting sound compared to metal piston heads.

• Reduced friction and wear: The included bearing reduces friction and prevents over-tensioning of the spring, which can lead to less wear on the gearbox over time.

• Improved stability: The six-hole ventilation design helps stabilize the piston during full-auto fire.

• Durable construction: Polycarbonate is a strong and durable material for the piston head. 

Important considerations

• Compatibility: This is a bore-up part and requires a compatible bore-up cylinder and other internal parts to function correctly.

• Installation: Proper installation requires technical skill, and it may be necessary to perform adjustments like dremeling or re-greasing for optimal performance, especially for high-power setups.

• Maintenance: Regular gearbox maintenance, including lubrication of the cylinder, is recommended to prevent issues like O-ring warping over time.
