Made in Italy, the FPS Softair XPAVP piston head is specifically engineered for high rate-of-fire (ROF) builds (30+ RPS) and acoustic damping. Precision CNC-machined from low-friction POM (polyoxymethylene) technopolymer, it features an ultra-lightweight profile to minimize gearbox stress during rapid cycling. Its specialized striking face is inward-sloped/conical toward the center, preventing cylinder head rubber from blocking the air ports while reducing overall impact noise. Utilizes an X-Ring (quad seal) for low-drag compression and comes paired with a technopolymer shim for precise Angle of Engagement (AOE) tuning. Fully Tokyo Marui compatible.
