Precision GBB Hop-Up Bucking
Developed for a stable, centered spin axis and a flatter, more consistent BB flight path. Available in two 70° material options so you can choose the version that best matches your climate, setup, and usage style.
The Clutch Precision GBB Hop-Up Bucking is designed around a refined internal contact profile that helps center the BB and apply hop in a more controlled and repeatable way. The result is a more stable spin axis, improved consistency, and tighter groupings downrange.
Both versions use the same performance-oriented geometry and function. The only difference is the material, allowing you to choose between better cold-weather grip or greater long-term durability.
Light Blue – Silicone 70°
The ideal choice for users who want maximum grip and stronger performance in cold or damp conditions. The softer and more compliant material helps maintain hop effect when standard rubber compounds may become less effective.
- Cold weather setups
- Winter and humid environments
- Users prioritizing stronger BB grip
- Heavier BB applications
Black – Rubber 70°
The more robust all-round option for users who prioritize durability, wear resistance, and long-term stability. This version is especially well suited for regular field use and higher round count setups.
- General-purpose GBB use
- High round count builds
- Users prioritizing durability
- Warm to moderate temperatures

Key Features
Compatibility
This bucking is designed around TM-spec GBB dimensions and provides an excellent drop-in fit for most VFC GBB platforms.
| Ideal fit | VFC GBB platforms and TM-spec based systems |
| Recommended use | Drop-in use in VFC systems |
| Not direct drop-in | WE Tech and GHK platforms |
WE Tech and GHK GBB systems use different hop-up specifications and internal dimensions. This bucking is not intended as a direct drop-in solution for those platforms. If you want to use this bucking in WE or GHK systems, we recommend using a dedicated tuning hop-up chamber or hop-up unit designed for TM-spec buckings.

Product Characteristics & Cosmetic Standards
Our products are manufactured using precision machining and industrial finishing processes. As a result, minor cosmetic characteristics may be present, including but not limited to light machining marks, tool traces, finish variations, minor surface marks, slight discoloration, or light surface oxidation where applicable.
In mechanical systems, slight movement, wobble, or play between components may occur due to designed tolerances and does not affect function or performance.
These characteristics are purely cosmetic or tolerance-related, fall within normal manufacturing standards of the airsoft industry, and do not constitute a product defect.
Returns or warranty claims based solely on such cosmetic or tolerance-related characteristics may therefore be declined in accordance with our return policy.
Light surface oxidation (rust), where applicable, is a normal material property and can typically be removed through routine maintenance (e.g., WD-40 and a soft brush).
