4UANTUM Friction Pro AEG hop up bucking

A little bit of marketing text

Designed for maximum consistency, the Friction Pro hop-up rubber focuses on creating a perfectly centered axis of rotation with every shot. Although based on a fairly traditional single-point design, the unique shape of the contact area generates enough friction to lift even heavy BBs up to 0.48 grams, while minimizing the contact area and ensuring there is no room for error. The result is a flat, consistent and accurate trajectory.

And now our experience

From our testing, the ideal bullet weight for this rubber band is 0.25g to 0.4g for AEG, for HPA we recommend 0.48g. It works well with most chambers (we installed it in RetroArms, Maxx, Begadi Nebo) and nozzles. The consistency of the bullets is really great both vertically and horizontally in semi and full auto (30 RPS). This orange bucking has become the go to bucking that we install in our kits.
