The Miyagawa Rubber Induction Hop-Up Bucking delivers an engineered domestic flight solution designed to achieve maximum accuracy and grouping stability in custom electric guns. Manufactured in Japan by Miyagawa Rubber, this high-tier packing is the official direct successor model to the legendary Arms Magazine Bullet Collection Test No.1 champion packing. It features an optimized internal induction ridge system designed to stabilize BB loading alignment and deliver uniform backspin.
This premium hop-up component serves two crucial engineering purposes:
  1. Induction Alignment Control: The specialized interior contact geometry perfectly channels each BB into the dead center of the barrel inlet, eliminating the microscopic loading variations that cause unexpected flyers and horizontal drift.
  2. Thermal Material Stability: Molded from premium-grade domestic silicone rubber with a 60-degree hardness rating, this packing maintains its exact flexible friction profile across cold or hot ambient temperatures, preventing performance drop-offs during long-range field strings.

Technical Specifications:

  • Material: High-durability premium domestic silicone rubber compound
  • Hardness Rating: 60 Durometer (Medium-Hard compound optimized for versatile field velocities)
  • Package Contents: 1x Miyagawa Rubber Induction Hop-Up Bucking
  • Compatibility: Standard Version 2 and Version 3 Tokyo Marui-specification AEG inner barrels and rotary hop-up chambers
  • Origin: 100% Made in Japan
  • Design: Direct engineering successor to the Arms Magazine high-accuracy test winner geometry
Tech & Safety Warning: Silicone buckings provide exceptional oil and low-temperature resistance, but they are highly sensitive to aggressive chemical cleaning agents. When performing maintenance or rebuilding your chamber array, avoid contact with harsh petroleum-based lubricants or industrial solvents to prevent material swelling or tearing.
