Hop-up Bucking Friction Pro | GBB | 4UAD

Hop-up Bucking Friction Pro | GBB | 4UAD – hop-up bucking for your replica

This hop-up bucking is developed for GBB replicas that require consistent BB trajectories. The Friction Pro from 4UAD provides controlled backspin on your BBs thanks to a carefully designed contact patch. The single-point contact gives your BBs stable rotation, resulting in flat and repeatable flight paths. If you notice that your current bucking produces irregular trajectories or struggles with heavier BBs, it is time to consider this GBB hop-up bucking.

Technical specifications

The Friction Pro bucking features an orange rubber compound with a specially shaped contact patch. The single-point design keeps the contact surface minimal while maximising grip on the BB. This bucking can handle BBs up to 0.48 grams thanks to the shape of the contact point. The construction focuses on centring the BB in the hop-up chamber for a straight spin axis.

Compatibility and application

This bucking is designed for GBB systems and fits standard hop-up units for gas blowback replicas. Replacing a bucking requires basic knowledge of your hop-up unit – you need to be able to remove the inner barrel and replace the old bucking. The Friction Pro works with both standard and advanced GBB builds where trajectory control and consistency are paramount. Note! Does not fit WE Hi-Capa.
