The Stalker Scorpion TAC-41 Piston!

STALKER:
After designing the Stalker Scorpion SRS and Scorpion VSR editions it was now time for the TAC-41 edition.

The Stalker Scorpion piston has an extremely modular design. It has all the options people could want for their piston. It 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 (shortstroke/shortpull) which in turn reduces the volume of your cylinder and joule output but benefits from a short pull and shorter piston travel.

Ultimate Part List :
1x Alluminium Piston Head
5x Alluminium Center Weights
1x Steel Piston Head
4x Steel Gold Weights
1x Piston Cup 
1x Brass Airbrake
1x Nut for Airbrake
1x STALKER engraved Spring Guide
1x Front Guide Ring
1x Rear Guide Ring
1x Sear End
1x O ring kit

The 6 piece setup allows for 12 different setups, by extending the piston with an additional weight it allows you to choose from 12 additional setups to choose from.

Here's a list for the 6 piece setups:

SRS Scorpion 62g (1x head alu, 5x mid section alu)
SRS Scorpion 76g (1x head alu, 1x mid section steel , 4x mid section alu)
SRS Scorpion 80g (1x head steel, 5x mid section alu)
SRS Scorpion 89g (1x head alu, 2x mid section steel , 3x mid section alu)

I’ll explain the features of this piston for you below.

The cups are 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 cups are available in two versions.

Black Cup

Lube piston cup with oil such as Motor oil, Sewing machine oil, or grease like TechT before use.

  • Zero loading friction.
  • Thumb Block Air Seal
  • Best Joule Output.
  • Fast Reloading (Lightest pull).
  • Fits SRS Scorpion as well

The piston comes with several body weights (depending on the product edition) that are interchangeable with each other to perfectly set up your SRS.

  • Available in aluminum anodized black, each piece weighs: 7 Grams
  • Available in coated gold, polished steel, each piece weighs: 21 Grams

Next to that, the piston head is available in these versions as well.

  • Aluminum anodized black, each head weighs: 8 Grams
  • Coated gold, polished steel, each head weighs: 24 Grams

This way you can configure the piston between ~65 to 148 grams, This way you can set it up for any kind of joule output.

Next to that, the piston comes with one adjustable airbrake.

1x Adjustable Airbrake made of Brass. (O-ring optional)

This is a non-tapered, fat, brass airbrake. This airbrake is the most "direct" working airbrake, once the airbrake enters the nozzle the piston immediately starts to slow down.

The airbrake 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 :  

  • Stalker TAC-41 Sear End Cap made of durable steel.
  • Front guide ring made of POM.
  • Stalker TAC-41, 9MM Laser engraved Stalker spring guide with top cut-out for the adjustable Airbrake.
  • 10- O rings for in between the weights or cylinder head to stop the weights from loosening by playing.

The size of the entrance of the Scorpion piston has been optimized to work best with Rapax and Silverback springs it might work just fine with other brand springs as long as these springs have the same diameter as the springs mentioned above.

Basically, if you like a plug and play piston or if you are a master of tinkering with your piston weights, airbrake, and cups to get the best performance, then the Stalker Scorpion is your best friend.
