This upgrade piston is manufactured from lightweight and durable aluminum alloy and serves as a direct replacement for the original plastic piston without requiring any modifications to the rifle. Thanks to its vacuum piston head design, air pressure generated during firing expands the sealing O-ring, allowing it to seal more effectively against the cylinder wall and improve compression. The piston is especially suitable for rifles equipped with stronger upgrade springs, where its increased mechanical strength significantly extends the service life of the entire assembly.
The piston is made from lightweight aluminum alloy, providing significantly greater strength and a longer service life than the original plastic component.
Six air channels direct air beneath the sealing O-ring, causing it to expand during firing for improved cylinder sealing.
The optimally sized sealing O-ring helps maintain high compression and consistent muzzle velocity.
The internal dimensions match the original piston, allowing installation without any modifications to the rifle.
Its increased durability makes this piston an excellent choice when installing stronger springs and other performance upgrades.
