The Kraken And Why We Started it!?

A Warm Welcome !

Hello Guys!
First of all i want you to send a warm welcome to our tech and crafting website which is full of tech and crafting guides from various people around the world. We hope you like it and having a great time reading here. Take a cup of coffee or tea while i explain when and why we started to make the Stalker Kraken SRS Chamber.

Let’s talk a bit about the Stalker Kraken SRS Hopup Chamber Design

Back in 2018 we shared a funny idea on the the Stalker facebook we had the idea to put a VSR bucking inside the fasthop chamber and there it all started… We found a way to design and make another 3D printed fasthop front piece that could carry a VSR bucking. The Kraken was born!

My idea became real and i played with the 3D front piece for a long time but my brain didn’t stop thinking about a complete chamber.. so i opened the design many times and see if i could work this idea out to make one full hopup chamber which could work perfectly inside the Silverback SRS A1.
I’ve spend hours to make something that was really looking good and started to make the first prototype chambers in CNC aluminium.

But as we all know the SRS is made to shoot with AEG type buckings and works extremely well with the colored Silverback buckings in combination with the Silverback FASThop and that is still one of the best setups around and three manufacturers send a new VSRS like hopup chamber to the market after i started with this idea but still these days i saw facebook posts of people that couldn’t get their setup straight or 100% sealed i read some facebook post titles on the SRS Owners Group here: (

Facebook Post Titles like these below are very common:

“OOoof my chamber is hard to install “
“i shoot to the left and to the right all the time please help”
“Hello i don’t have 100% seal in my SRS setup”
“Which bucking is best to use with what nub??”
“Which mods should i use.. PTFE tape on the bucking or on the barrel?”
“i throw the SRS A1 out of the window and going to play a VSR again”
“i’ve sold my SRS A1 cause i couldn’t get it straight”

So my second mission started.. Upgrade my Stalker SRS Kraken chamber design to something that’s always straight and always 100% sealed without having to buy numerous other materials and use allot of mods on a bucking or barrel to get the set sealed or straight. My goal was to make something for the beginning or advanced SRS A1 User, one hopup to make evereyone happy and enjoy their SRS A1 at the most. i’ve made a one piece action amry like chamber for SRS but sadly machines couldn’t make this design as they could not drill the groove for the VSR tab deep enough, i had to split the hopup chamber make two halves and start over again. Finaly after some months i changed my design and first printed some prototype 3D prints and
i’ve tested 3D printed Kraken prototypes along with my friends and people that also helped me backing this project for some months. i gathered the feedback of the community and feedback from the prototype testers and right now we are in the final steps of the real final product! We really didn’t feel like we had to rush this chamber to bring it to the market so yes it’s true, Some brands tought we had a good idea or maybe were already busy with a VSRS like hopup design for the SRS and dropped their models on the market but looking as a designer to the current existing srs chamber models on the market i still think the Stalker Kraken SRS Chamber will be a unique piece of art that is the most modulair and Innovative chamber that will exist in the SRS community.
