4uantum Friction Pro High-Performance GBB Bucking and Nub
Precision-engineered GBB bucking delivering consistent spin, improved accuracy, and reliable hop performance
Engineered for precision and consistency, the 4uantum Friction Pro High-Performance GBB Bucking is a premium hop-up upgrade designed to maximise the performance of your gas blowback (GBB) airsoft platform.
At the core of its design is a uniquely contoured contact patch that creates a perfectly centred axis of spin with every shot. This ensures exceptional shot-to-shot consistency, tighter groupings, and improved overall accuracy. Unlike conventional buckings, the Friction Pro minimises unnecessary contact surface, reducing inconsistencies and delivering a flatter, more stable BB trajectory.
Built from high-quality rubber, this bucking generates optimal friction, allowing it to effectively lift heavier BBs—up to 0.48g—without sacrificing precision. The result is enhanced range, improved hop efficiency, and reliable performance across a wide variety of GBB platforms.
Whether you’re upgrading for competitive play or fine-tuning your setup, the Friction Pro bucking offers a simple yet highly effective way to achieve consistent, accurate shots with every pull of the trigger.
