Laylax Prometheus POM Piston Head for Tokyo Marui Next Generation New Ver.2

Achieve optimal air seal efficiency, consistent FPS output, and long-term mechanical durability in your advanced electric blowback platform with the Laylax Prometheus POM Piston Head for Tokyo Marui Next Generation New Ver.2! Specially developed in Japan by Laylax under their world-renowned Prometheus upgrade label, this precision internal component is engineered exclusively for Tokyo Marui Next Generation Recoil Shock (NGRS) platforms.

High-Density POM Polymer & Impact Absorption Unlike metal piston heads that transfer harsh kinetic shock directly to the gearbox shell during cycling, this Prometheus component is CNC-milled from premium Polyoxymethylene (POM) polymer. POM material combines exceptional structural rigidity with a low coefficient of friction and superior energy-absorption properties. By dampening the impact of the forward piston stroke against the cylinder head, it helps protect delicate NGRS gearbox components from cracking under stress while ensuring ultra-smooth sliding motion inside the cylinder bore.

Dynamic Air-Porting & Airtight Compression The front face of the piston head features precisely placed air ports that route pressurized air directly behind the sealing O-ring as the piston thrusts forward. This dynamic air distribution forces the high-grade rubber O-ring outward against the cylinder wall during compression, creating an instantaneous, leak-free seal for maximum FPS velocity and tight shot groupings. On the return stroke, the ports allow air to pass through freely, reducing back-pressure vacuum drag and increasing overall cycling efficiency.

Tailored for Tokyo Marui NGRS Platforms Engineered specifically for TM NGRS models featuring the New Version 2 gearbox design—including M4, HK416, HK417, and SCAR-L/H Recoil Shock series—this piston head fits seamlessly into your upgraded internal assembly. It functions effortlessly with both stock factory setups and upgraded high-speed or high-torque spring configurations.

Whether you are fine-tuning a precision MILSIM recoil shock rifle or protecting your investment against internal wear during rapid semi-automatic strings, the Laylax Prometheus POM Piston Head for Tokyo Marui Next Generation New Ver.2 delivers the Japanese engineering excellence needed to unlock peak NGRS performance.

Tech Tip: When installing, ensure a small amount of high-quality silicone grease is applied to the O-ring to ensure a long-lasting, airtight seal.
