4UANTUM Friction Pro High Performance Hop-Up Bucking - GBB August 2020 Reinforced steel pinionDesigned to achieve ultimate consistency, the 4UAD Quantum Friction Pro hop up bucking focuses on creating a perfectly centred 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 theres no room for error. Resulting in a flat, consistent, and accurate trajectory!
