Product Description:

Madbull 60 Degree Normal Shark Hopup Bucking (Blue). Standard shark-fin internal teeth design for consistent backspin. 60 Degree rubber is softer than typical 80-90 degree rubber — easier installation, better air seal at standard FPS ranges. Suitable for AEGs running sub-400 FPS with 0.20-0.28g BBs.

Which Hardness Should You Choose?

Degree Best For Trade-off
60° (this product) Standard AEG, sub-400 FPS, 0.20-0.28g BBs, cold weather play Softer seal = easier cycling on stock springs; wears faster than harder compounds (expect 15-20K rounds)
80°+ (Red Shark Accelerator) 400+ FPS, DMR/sniper, 0.30g+ heavy BBs Longer lifespan, heavier backspin; may jam on low-FPS/stock setups

Green Gas vs AEG Considerations

  • AEG users: 60° is ideal for standard builds (330-400 FPS). Pair with a tightbore inner barrel (6.01-6.03mm) for max consistency.
  • GBB users: Verify you need an AEG-cut bucking. Most GBB pistols (Hi-Capa, Glock, 1911) use VSR/G-Series cut buckings. This AEG-cut bucking will NOT fit GBB hop chambers.

Common Pairings (based on verified customer orders at eHobbyAsia)

  • MadBull Blue Bucking + PDI 6.03mm Barrel — balanced accuracy upgrade for outdoor M4 builds
  • MadBull Blue Bucking + Laylax Strike Chamber — for AK users who want to upgrade the entire hop unit in one go
