FPS PISTON HEAD BEARING IN ERGAL WITH DOUBLE OR LIGHTENED FOR HIGH SPEED

Description

The FPS TPAVN is a high‑performance CNC‑machined ERGAL piston head designed to maximise air efficiency, consistency and durability inside any Marui‑spec AEG. Built for players who want smoother cycling, stronger air seal and improved rate of fire, this is one of FPS’ most advanced piston head designs.

The front‑facing ventilation ports expand the O‑ring during each shot, ensuring that every bit of air inside the cylinder is pushed forward to propel the BB — delivering tighter FPS consistency and better overall efficiency. The double O‑ring configuration further enhances sealing performance, especially in upgraded builds.

The integrated ball‑bearing system reduces spring tension during compression and release, helping maintain spring health and improving gearbox smoothness. When paired with a ball‑bearing spring guide, it forms an optimal low‑stress setup for long‑term reliability.

Machined from CNC ERGAL (7075 aluminium) and anodized for a smooth, low‑friction finish, the TPAVN is built for durability, precision and high‑speed performance. 100% Made in Italy — 100% Marui compatible.
