4UAD SmartAirsoft 4UANTUM Friction Pro High-Performance AEG Hop-Up Bucking

Out of Stock

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!
