The TopMax White Delrin Piston Head is a high-precision compression component engineered by TopMax Elaborazioni specifically for the Tokyo Marui Next Generation Recoil Shock (NGRS) platform. CNC-machined from a specialized Delrin (POM) compound, this piston head offers an incredibly low net weight of 3.27 grams, reducing reciprocating mass to improve both cyclic speed and the longevity of the gearbox shell. The White variant features a specialized front shape designed to generate a light air cone, which focuses air volume for superior compression within the cylinder compared to flat-face alternatives. Each unit is manufactured in Italy and rigorously stress-tested with high-power springs to ensure it maintains a perfect air seal under professional-grade configurations.

Technical Specifications:

  • Material Construction: CNC-machined from high-density White Delrin (POM) for a low-friction, self-lubricating surface.
  • Weight Efficiency: Ultra-lightweight design at 3.27g, engineered to decrease striking mass and gearbox stress.
  • Aerodynamic Profile: Features a conical front face designed to generate an air cushion for enhanced compression efficiency.
  • Impact Management: Specifically designed with a reduced stroke compared to standard heads to distribute impact force more gradually across the cylinder head pad.
  • Ventilation System: Equipped with six radial ventilation holes that ensure rapid O-ring expansion for a near-instant air seal upon the compression stroke.
  • Thrust Bearing Interface: Includes a high-quality Delrin bearing/axial thickness to eliminate spring torsion and reduce vibration.
  • Modular Insert: Features a redesigned ERGAL and Delrin CNC insert that allows the head to be mounted on almost any aftermarket NGRS piston.
  • Platform Compatibility: Optimized strictly for Tokyo Marui SRE/NGRS gearboxes (M4, HK416, SCAR series).
