Precision hop for gas blowback
The 4uantum Friction Pro is built by Taiwanese specialist 4UAD specifically for gas blowback pistols and rifles. Its rubber compound and single-point contact geometry create a perfectly centred axis of spin on every shot, which is the key to tight, repeatable groupings from a GBB platform.
Lift heavier BBs with confidence
The unique contour of the contact patch generates enough friction to hop heavy BBs of up to 0.48g, while minimising surface contact to remove inconsistency. The result is a flatter, more predictable trajectory that helps you reach out further with real accuracy.
Better seal, better shots
An improved air seal keeps your FPS stable and makes each gas charge more efficient, so you get dependable performance from the first shot to the last in a magazine. It fits Tokyo Marui, VFC and KJW spec hop-up chambers and comes complete with a matched nub.
Fit and forget
Installation involves stripping the hop-up unit, so if you would prefer expert fitting our airsoft techs in Kent can install and tune it. Find more upgrade parts in our airsoft accessories range.
