Specification

Serious accuracy for your AEG

The 4uantum Friction Pro AEG bucking is a next-generation hop rubber from Taiwanese specialist 4UAD, engineered for maximum consistency and durability. Its precision-moulded internal design creates a centred axis of spin on every shot, which is what delivers tight, repeatable groupings downrange.

70 degree firmness that just works

The 70 degree compound is a well-judged middle ground that performs reliably across FPS ranges. Whether you are running a snappy CQB carbine or a longer woodland DMR-style build, it holds hop consistency where cheaper buckings drift.

Hop heavier, shoot flatter

The unique contact patch contour generates enough friction to lift heavy BBs of up to 0.48g while minimising contact surface to remove error. That means a flatter, more predictable trajectory and better hit probability at mid to long range.

Complete the upgrade

It fits standard AEG hop-up units and comes with a matched nub. For expert fitting and tuning, see our airsoft repair service in Kent, and browse more internals in our airsoft accessories range.

Frequently asked questions

What firmness is this bucking?

This is the 70 degree version, a versatile firmness that performs consistently across a wide range of FPS from CQB builds to longer-range woodland setups.

Is it compatible with my AEG?

Yes for the vast majority of AEGs. It is designed to fit standard AEG hop-up units and inner barrels, which covers most V2 and V3 gearbox platforms.

What comes in the pack?

You receive the Friction Pro AEG bucking together with a matched hop-up nub, giving you both parts required to complete the upgrade.

How does it improve accuracy?

The contoured contact patch creates a centred axis of spin and lifts BBs up to 0.48g, producing a flatter, more consistent trajectory and tighter shot groups.

Can you fit it for me?

Yes. Fitting means stripping the hop-up unit, so if you prefer, our in-house Kent techs can install and tune the bucking as part of a service.
