The 4UANTUM Friction Pro, developed by 4UAD Smart Airsoft, is a high-precision hop-up system engineered to deliver R-hop-level consistency with a standard drop-in installation. This bucking focuses on creating a perfectly centered axis of spin for every shot by using a refined single-point contact design. Despite its minimized contact surface, the unique contour of the patch generates enough friction to lift heavyweight ammunition up to 0.48g. Constructed from a proprietary, oil-resistant MBR compound, the Friction Pro offers superior durability and a high-performance air seal that minimizes FPS variation across long strings of fire.

Technical Specifications:

  • Material Construction: Manufactured from a high-resistance MBR (Nitrile-based) compoundspecifically formulated to resist swelling from silicone oil and grease.
  • Contact Geometry: Features a unique, contoured single-point contact patch designed to center the BB and eliminate spin deviation.
  • Hardness Rating: 70 Degree (Shore A) firmness, providing high-speed stability and resistance to deformation in high-stress builds.
  • Lifting Capacity: Specifically engineered to provide consistent lift for a wide range of BB weights, effectively handling up to 0.48g BBs.
  • Integrated Nub: Includes a matching contoured tensioner (nub) designed to distribute pressure evenly across the bucking's specialized contact patch.
  • Air Seal Efficiency: Features a precision-molded inner lip that reduces air blowby, often resulting in a slight FPS increase over stock units.
  • Operating Range: Optimized for builds shooting up to 2 Joules, providing a flat and repeatable trajectory for both indoor and outdoor environments.
  • Standard Compatibility: Designed as a direct fit for most Tokyo Marui-spec AEG hop-up chambers and inner barrels.
