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!   The friction master Hop leather is designed to achieve the best stability, focusing on producing a perfectly centered rotation axis every time you shoot. Based on a relatively traditional single pressure point design, the unique profile of its contact surface produces enough friction to effectively lift even heavy BB bullets weighing up to 0.48 grams, while minimizing the false contact area to ensure that there is no room for misplacement of the pressure point. This forms a straight, consistent and precise trajectory!
