The AirsoftPro piston head is designed exclusively for New Bore-Up cylinders. Its aluminum construction provides excellent durability while keeping weight low. Six air channels direct compressed air beneath the main O-ring, causing it to expand during firing for an improved air seal. A second O-ring is used for precise centering of the piston head inside the cylinder, helping to ensure smooth piston movement. The piston head also features a ball bearing that allows the spring to rotate during compression, reducing resistance while cocking. A special locking washer between the piston head and piston helps prevent the piston head from loosening during operation.
