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.
