The Miyagawa Rubber Long Hanging Fat Silicone Set provides an engineered domestic trajectory solution designed to maximize flight stabilization, extreme hop lift, and heavy bb rotation in AEGs. Manufactured in Japan by Miyagawa Rubber, this premium choice introduces an extended flat-hop layout that dramatically elongates the physical friction contact path relative to standard factory setups.
This high-performance internal component serves two crucial engineering purposes:
  1. Maximum Backspin Transfer: The Fat architecture features significantly thickened and widened internal holding ridges compared to the Middle or Slim series. This maximizes surface-area traction, allowing you to easily hop heavy-weight ammunition (0.28g to 0.33g+) without choking your air-seal or crushing your FPS.
  2. Two-Point Stabilization Alignment: Employs a precision-molded 2-point internal support channel that seats each chambered projectile perfectly dead-center. This acts to continuously damp vibration, entirely neutralizing horizontal side-to-side shot dispersion and sudden flyers.

Technical Specifications:

  • Material: High-durability premium domestic silicone rubber compound
  • Hardness Rating: 60 Durometer (Medium-Hard formula optimized for high-stress pre-cocking and robust tear resistance)
  • Package Contents: 2x Long Hanging Fat Silicone Hop-Up Buckings, 1x Custom-Matched Flat/Cylindrical Press Nub
  • Compatibility: Standard Version 2 and Version 3 Tokyo Marui-specification AEG inner barrels and rotary hop-up chambers
  • Origin:


    100% Hand-Crafted in Tokyo, Japan
  • Design: Heavy wide-ridge profile engineered explicitly to handle high-torque setups and heavier weight classes
Tech & Safety Warning: Due to the high-friction geometry of the Long Hanging Fat internal ridge array, hop-up dial adjustment is highly sensitive. Applying excessive down-force on a fully maxed chamber arm can cause immediate nozzle jamming or mid-cycle piston stripping. Dial your hop settings incrementally during initial field tuning.
