DCI GUNS AEG Side Air Ventilation Piston Head

Piston Head for AEG Features: 1) Side Air Vent System - Through holes on the sides of the piston head prevent excessive expansion of the O-ring and provide constant speed under all lubrication conditions. It also reduces the negative pressure generated by backing the piston, which contributes to high cycle and high efficiency. Thanks to this side air vent system and the use of GAW FRUS O-rings, we were able to develop a piston head with low friction resistance and a stable initial speed. Speed ​​stability is an important factor in improving accuracy. Low friction resistance is also an important factor in saving battery power and reducing motor brush wear. 2) GAW FRUS O-ring: Specially treated O-ring with a coefficient of kinetic friction less than 1/5 the coefficient of conventional NBR (Nitrile Rubber) O-rings. Its low adhesion to metals prevents the O-ring from sticking to the cylinder. Ideal for high firing rates. 3) Compatible with GAW AOE trim spacers for AEG: AOE trim spacers can be added without modification. The AOE adjusting spacer is not included. 4) Adapted design to the inner wall of the cylinder: the piston head has a slightly smaller diameter and a rounded shape at the front and back to avoid damage to the inner wall when the piston is moves inside the cylinder. 5) High quality bearing to ensure smooth running. 6) Material:
