The X-RING AEG (TPAVP) is a reinforced polymer piston head designed for high rates of fire (ROF) and noise reduction in airsoft guns. Created by the Italian company FPS Softair, this piston head is ideal for guns with a firing rate of over 30 rounds per second. Its unique design reduces the weight of the piston, resulting in lower mechanical stress and less noise. The front part is conically shaped to prevent the ventilation holes from being blocked by the cylinder head bumper, ensuring an optimal air volume and an effective anti-vacuum system without sacrificing power.
