4UAD Friction Pro-High Performance GBB Hopup Bucking

4UAD Friction Pro is a high-performance rubber designed for GBB weapons, the whole idea of ??which is based on one thing: the smoothest and most centered bullet trajectory for every shot.

The contact surface shape is optimized to produce a consistent and centered spin on the ball. The contact is aggressive enough to provide the necessary friction even for heavier balls, up to 0.48g, but at the same time the contact surface has been intentionally kept small. This reduces error sensitivity, side spin and uneven pitch. The end result is a consistent, straight and repeatable trajectory, which is reflected above all in better hitting accuracy and consistent performance from shot to shot.

Another plus is that a compatible printer is included, so installation is possible without hunting for separate compatible parts.
