4UANTUM Friction Pro-High Performance GBB Bucking

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

While still based on a rather traditional single-point  contact design, the unique contour of the contact patch generates enough friction to even lift heavy BBs up to 0.48g, while minimizing contact surface to ensure there’s no room for error. Resulting in a flat, consistent, and accurate shot trajectory!
