Perfect fitment in Airsoftphilosopher’s Hopup window

Having a high-quality barrel and bucking inside of your RIF is important, but even more important is their compatibility to each other. If the bucking does not fit perfectly into the Hopup window of the barrel, or the chamber applies the downward pressure in the wrong place, the Hopup bucking cannot use its full potential.


So Airsoftphilosopher carefully designed their products in order to achieve the best possible results together.


As the picture shows, the patch covers the whole length of the window, while there is still a small gap for the bucking patch to move up and down without tension. Even the barrel edges are chamfered for a longer bucking life and enough space for the downward motion.


Designed for the Maximum

The Concave Bucking is designed to reach the physical limits of accuracy and range. It provides a 6.6 mm long contact patch in order to guide the BB perfectly and apply precise backspin.


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

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 spot.


Perfect airseal


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


So, the Airsoftphilosopher concave bucking feeding lip is tighter than other buckings to provide perfect air seal.  The special design reduces feeding problems.


Additional 3D impress on the outside improves the flight fit inside the chamber.
(Every chamber has slightly different dimensions, so if air seal is not good with your chamber, wrap one or two layers of Teflon tape on the outside)


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.


Polished surface


Each bucking has a polished surface to provide highest tolerance and consistency.
