4UANTUM Friction Pro High Performance GBB Hop Up Rubber

The 4UANTUM Friction Pro High Performance GBB Hop Up Rubber is designed to achieve ultimate consistency in every shot.

The 4UANTUM Friction Pro bucking focuses on creating a perfectly centred spin axis in every shot. Although based on a fairly traditional single-point design, the unique contour of the contact area generates enough friction to give even heavy BBs up to 0.48 grams perfect spin, while minimising the contact area to ensure there is no room for error.

The result is a flat, consistent and accurate trajectory!
