4UANTUM HOP-UP BUCKING GBB MODEL FRICTION PRO HIGH PERFORMANCE

Designed to achieve ultimate consistency, the Friction Pro hop-up bucking focuses on creating a perfectly centered axis of spin in every shot.

While based on a rather traditional single-point design, the unique contour of the contact patch generates enough friction to even lift heavy BBs up to 0.48 grams, while minimizing contact surface to ensure there’s no room for error.

Made from  NBR ( Nitrile Butadiene Rubber)

All this combined result in a flat, consistent, and accurate trajectory! 

- Hardness 70°
