FPS Reinforced technopolymer piston head designed for high ROF and to increase the silence of the AEG

Description

The FPS TPAVP is an ultra‑light reinforced technopolymer piston head engineered for high‑rate‑of‑fire builds and quieter AEG operation. Designed with a minimal striking surface and precision‑shaped impact cone, it reduces mechanical noise while maintaining perfect airflow and reliability — ideal for rifles running 30+ RPS.

Its extremely low weight reduces the overall moving mass of the piston assembly, cutting mechanical stress and improving cycle smoothness. The conical striking face ensures the ventilation ports remain unobstructed by the cylinder head rubber, preventing vacuum effect without leaving excess dead air. The result: stable FPS, faster cycling and a noticeably quieter shot signature.

For extreme ROF setups, FPS recommends pairing the TPAVP with the included technopolymer washer to further reduce impact mass. As always, it’s 100% Marui‑compatible and 100% Made in Italy, delivering the precision and durability FPS is known for.
