RetroArms CNC POM Piston for Tokyo Marui NGRS (Next Gen Recoil Shock) • 14.5 Steel Teeth

The ultimate durability upgrade for your recoil shock system. Manufactured by the CNC precision experts at RetroArms, this Next Gen piston is engineered specifically for Tokyo Marui NGRS (Next Generation Recoil Shock) gearboxes. Combining a lightweight, self-lubricating CNC-machined POM body with a heavy-duty 14.5 full steel teeth rack, it easily withstands the high-stress demands of active blowback and recoil mechanisms.

  • Tokyo Marui NGRS Optimized: Drop-in upgrade compatibility for TM Next Generation Recoil Shock platforms.
  • CNC-Machined POM Body: Milled from a single block of premium polyoxymethylene for low-friction operation and extreme impact resistance.
  • 14.5 Hardened Steel Teeth: High-strength steel rack protects your drivetrain from stripping under heavy recoil stress, featuring pre-corrected Angle of Engagement (AoE) geometry.
  • Smooth Cycling: Significantly reduces mechanical drag within the cylinder to optimize rate of fire and battery efficiency.

Engineered for Tokyo Marui Next Generation Recoil Shock (NGRS)

Tokyo Marui's NGRS platforms deliver unparalleled realism, but the internal mechanical stress of the recoil shock system demands high-tier component upgrades. The RetroArms CNC POM Next Gen Piston is purpose-built to handle this exact environment. Designed to replace standard factory pistons, this component reinforces your gearbox core, ensuring flawless cycle timing and complete reliability even when running higher voltage batteries or upgraded springs.

Premium CNC-Milled POM Construction

Unlike budget injection-molded pistons that suffer from structural warping under pressure, RetroArms manufactures this piston body from a single solid block of high-grade engineering POM (polyoxymethylene) using precision CNC milling. POM is renowned for its self-lubricating properties, ultra-low friction coefficient, and exceptional dimensional stability. This ensures the piston glides perfectly straight along the gearbox tracks, minimizing wear on your cylinder assembly.

Indestructible 14.5 Steel Teeth Rack with Pre-Corrected AoE

The beating heart of this piston is its heavy-duty full steel teeth rack. Featuring a 14.5-tooth configuration, the geometry is pre-optimized for proper Angle of Engagement (AoE) right out of the box. By modifying the standard 16-teeth layout to a pre-corrected 14.5 profile, RetroArms ensures your sector gear grabs the piston at the absolute best mechanical angle, distributing the stress evenly across the hardened steel teeth and eliminating premature gear failure.
