Designed for R-Hop systems


The Flat Bucking is designed to let you use R-Hop and similar Hopup methods. It is totally flat at the inside and applies even pressure


Best results are achieved with the Airsoftphilosopher VSR Chamber or the Maxx Model AEG chamber with concave nub.

Note: Most chambers are not designed for big hop windows and bridged barrels. Please make sure the Hopup arm and nub applies pressure at the correct position.

Perfect airseal


Every Hopup bucking has two main tasks:
Applying perfect Hop and providing airseal.


So the Airsoftphilosopher flat bucking feeding lip was designed to provide perfect airseal without causing feeding problems.


The additional 3D impress on the outside improves the airseal inside the chamber.

Special developed material


The durable silicone rubber is designed to create perfect friction between BB and Bucking. The large contact area of the patch allows it to use very soft rubber which creates perfect air seal and is still capable to Hop the heaviest weight BBs.


Due to the special compound, the silicone rubber has a higher compression set stability and reliably returns to its starting position even after a long exposure.
