4UANTUM Friction Hop-Up Bucking by 4UAD

The hop-up bucking 4UANTUM Friction for GBB is designed for maximum consistency and accuracy with every shot. This bucking ensures a perfectly centered spin on each BB, providing a steady trajectory with every pull of the trigger.
Although it draws from a traditional single-point design, the specialized contour of the contact patch generates enough friction to hop even heavy BBs up to 0.48 grams.
By minimizing the contact surface, it eliminates errors, ensuring each shot is flat, consistent, and highly accurate.
