Perfect fit in the Airsoftphilosopher hop-up window

Having a high-quality, properly cut inner barrel inside your airsoft replica is important, but even more important is their compatibility with each other. If the cut does not perfectly match the hop-up window of the barrel, or if the chamber applies downward pressure in the wrong place, the hop-up bucking cannot reach its full potential.

That is why we carefully design our products to achieve the best possible results when used in the correct setup.

As shown in the image, the patch covers the entire length of the window, while still leaving a small gap so the patch can move up and down without tension. Even the barrel edges are chamfered for longer service life and sufficient space for downward movement.


Designed for Maximum Performance

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

The best results are achieved with the Airsoftphilosopher VSR chamber or the Maxx Model AEG chamber with a concave nub.

Note: Most chambers are not designed for large hop-up windows and bridged barrels. Make sure that the hop-up arm and nub apply pressure in the correct position.


Perfect air seal

Each hop-up bucking has two main tasks:
Applying perfect hop and providing an air seal.

Therefore, the feeding lip of the Airsoftphilosopher concave bucking is tighter than other buckings to provide a perfect air seal. The special design reduces feeding issues.

Additional 3D printing on the exterior improves the tight fit inside the chamber.
(Each chamber has slightly different dimensions, so if the air seal is not optimal with your chamber, wrap one or two layers of Teflon tape around the outside.)

Specially developed material

The durable silicone rubber is designed to create perfect friction between the BB and the bucking. The large contact area of the patch allows you to use a very soft bucking that creates a perfect air seal and is still capable of lifting heavier BBs.

Due to the special compound, the silicone rubber has greater compression stability and reliably returns to its original position even after prolonged use.

 
Polished surface

Each bucking features a polished surface to provide maximum tolerance and consistency.
