Product Description:
Madbull 60 Degree Shark Accelerator Hopup Bucking (Red). Softer rubber construction with shark-fin internal teeth for aggressive backspin on heavy BBs (0.28g+). 60 Degree rubber is softer than standard 80-90 degree rubber, making it easier to install and providing better air seal on lower-FPS setups. Includes 2x hop-up rubbers.

Common Pairings (based on verified customer orders at eHobbyAsia)

-
MadBull Shark Bucking + Prometheus Flat Nub — flat-hop conversion for heavier BBs without replacing the entire chamber
GBB Compatibility Warning
-
GBB users: This is an AEG-cut hop up bucking. Most GBB pistols (Hi-Capa, Glock, 1911) use VSR/G-Series cut buckings. Verify your hop chamber cut type before ordering.
-
CO2 users: Higher pressure can accelerate wear on 60-degree rubber. Consider 80-degree alternatives for CO2 setups.
