The Stalker Scorpion Piston For VSR-10 / SSG-10
The Stalker Scorpion piston is a unique concept where 6 weights form the body itself and as the piston itself is made up of these weights, it is also possible to extend the piston with additional weights (short stroke) which in turn reduces the volume of your cylinder and joule output but makes loading your VSR10/SSG10 a lot shorter by each weight you add.
The 6 piece setup allows for 12 different setups, by extending the piston with additional weights it allows you to choose from a lot more additional setups to choose from. You can lower the joule or higher the joule by removing or adding weights, or change the guide rings and let them act as different shims to make the piston shorter or longer to your preference.
Here's a list for the 6 piece setups:
|VSR Scorpion 43g (1x head alu, 5x mid section alu)|
|VSR Scorpion 50g (1x head alu, 1x mid section steel , 4x mid section alu)|
|VSR Scorpion 54g (1x head steel, 5x mid section alu)|
|VSR Scorpion 58g (1x head alu, 2x mid section steel , 3x mid section alu)|
|VSR Scorpion 61g (1x head steel, 1x mid section steel , 4x mid section alu)|
|VSR Scorpion 65g (1x head alu, 3x mid section steel , 2x mid section alu)|
|VSR Scorpion 68g (1x head steel, 2x mid section steel , 3x mid section alu)|
|VSR Scorpion 72g (1x head alu, 4x mid section steel , 1x mid section alu)|
|VSR Scorpion 76g (1x head steel, 3x mid section steel , 2x mid section alu)|
|VSR Scorpion 79g (1x head alu, 5x mid section steel)|
|VSR Scorpion 82g (1x head steel, 4x mid section steel , 1x mid section alu)|
|VSR Scorpion 90g (1x head steel, 5x mid section steel)|
I’ll explain the features of this piston for you below.
The cup is made of durable high quality rubber and have been tested and adapted to have the best performance with the currently available cylinders on the market.
The piston comes with several body weights that are interchangeable with each other to perfectly set up your VSR10/SSG10.
- Available in aluminum anodized black, each piece weighs: 3 Grams
- Available in coated gold, polished steel, each piece weighs: 11 Grams
Next to that, the piston head is available in these versions as well.
- Aluminum anodized black, each head weighs: 7 Grams
- Coated gold, polished steel, each head weighs: 17 Grams
This way you can configure the piston between 43 to 90 grams, This way you can set it up for any kind of joule output.
Next to that, the piston comes with 1 adjustable brass airbrake (4gram) but the Scorpion SRS/VSR-10/SSG-10 Piston Stinger Tapered Airbrake - Brass with article code ST-060-N also fits this piston.
Both airbrakes are held with a nut underneath the cup against the piston head to keep it in place after you have adjusted it to your liking.
The adjustable airbrake is there to adjust the piston’s speed at the very end of its movement to reduce the time of air escaping the cylinder and to reduce some piston impact noise when it hits the cylinder head.
Other parts that are included :
- Sear End Cap made of stainless steel (15gram)
- 10- O rings for in between the weights or cylinder head to stop the weights from loosening by playing.
- Front and Back guide rings made of POM.
- 9MM Laser engraved Stalker spring guide with top cut-out for the adjustable Airbrake.
The size of the entrance of the Scorpion piston has been optimized to work best with Rapax springs it might work just fine with other brand springs as long as these springs are 9MM in diameter.
Basically, if you like a plug and play piston or if you are a master of tinkering with your piston weights, airbrakes to get the best performance, then the Stalker Scorpion is your best friend.
Important note! : In our intensive testing with various cylinders we noticed that the cylinder inner diameter various between all brands. This piston will work in all cylinders that are TM Spec! Edgi or PDI(non bore up) will not work! Due to the different cylinder diameters you can expect a lower or higher joule output then what springs are mentioning. Lower outputs generaly have less noise but need a stronger spring or spring tensioners to accomplish the needed Joules.
