Material:
Silicone rubber
Hardness:

VSR-10 chamber
Only works with Airsoftphilosopher barrels.
Recommended FPS:

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.

Sturdy, Easy to Set Up, and Looks Great
Color: Grey, Size: 34" - 3 Panel
I’m really happy with this RANTILA 3-panel room divider. It was simple to set up, stands securely on its own, and gives plenty of privacy. The height is perfect, and the panels look clean and modern in my space. It’s lightweight enough to move around but still feels sturdy. Overall, a great divider that works exactly as I needed.

Not 6 ft
Color: Grey, Size: 34" - 3 Panel
I bought this for filming my auditions. I am 5’4” .The height lists is 6 ft but the fabric only reaches 5’9 1/2 “!
when I must film myself head to toe, the top bars are showing. It’s easy to set up. But when I film I must tilt my camera to keep the top bars out of frame which is not acceptable.

Perfect for what I needed - getting a 2nd one.
Color: Black, Size: 22" - 4 Panel
Putting it together was a BEE-OTCH!! Yes, one of the tubes had the top cap installed at the wrong end (& getting it off required tools), and yes, stretching the fabric to get the screws in was incredibly hard...but am I buying another one? YES! After all is said and done, this is a great room divider. I opted out of installing the paddle feet & it still works perfect. It won't filter light all that great and even though it stands on its own, it can be blown over easily - but for the price? Excellent. If I wanted a heavy duty, thicker, more expensive one, I would've bought one.
The 2nd one is on the way.
Perfect height, no weird smell, nice and light and easy to move around.

WHERE HAVE YOU BEEN 😊
Color: Grey, Size: 34" - 3 Panel
I purchased RANTILA 3 Panel Room Divider, 6 Ft Tall Folding Privacy Screen Freestanding Room Partition Wall Dividers, 102''W x 20''D x 71''H, Grey. For outdoor use on my patio is perfect . PRIVACY!!! YAY!
It was packaged very carefully. There were no missing parts. Instructions were there but I still had to use the video visually. A few screws would not screw in. So I used a hammer with a few good taps that helped using the screw driver. 😊 It was easy putting it together following the directions. Everything is well made. Love the height, functionality and it’s definitely light it works.
Thank you
