4UANTUM FRICTION PRO - GBB

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. Resulting in a flat, consistent, and 
accurate trajectory! (For Marui GBB Spec)
