Flat VSR bucking and concave nub 60º (grey)

Designed for R-Hop systems

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

Best results are achieved with the Airsoftphilosopher VSR Chamber (Coming soon) 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 air seal

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

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

The additional 3D emboss on the outside improves the air seal inside the chamber.

Specially 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.
