Ball Bearing POM Piston Head for Marui Next Gen M4/SCAR – FPS Softair

FPS Softair POM piston head with ball bearing and double O-ring, designed for Tokyo Marui Next Gen Recoil Shock gearboxes in M4 and SCAR replicas. Its lightweight POM body is combined with an Ergal screw retainer and bearing cage, a steel thrust bearing and a steel spring retainer: a robust part, made entirely in Italy, for overhauling or upgrading the compression system of Next Gen replicas.

How it works

The thrust bearing lets the spring rotate freely as it compresses and releases, reducing torsion and friction in the piston assembly. The double O-ring keeps the seal inside the cylinder, which is what consistent compression shot after shot depends on.

Installation

Next Gen Recoil Shock gearboxes have their own dedicated parts, different from those of traditional AEG gearboxes: this piston head is made specifically for Tokyo Marui M4 and SCAR replicas of this series and replaces the original one.

In the field

Next Gen replicas are chosen for their realistic recoil and work hard in games: a ball bearing piston head with Ergal and steel components is the right basis for a thorough overhaul of the compression system or for a more complete upgrade.
