The new Stalker Scorpion piston for the SRS!

Key features:

  • Modular piston with adjustable weight (from ~65 to 148 grams)
  • Silences your SRS
  • Increases joule/FPS consistency
  • Adjustable airbrakes for optimal fine-tuning
  • SRS short-stroke option for faster reloads and shorter bolt pull.
  • Works with Open Piston Sear

The piston includes 2 adjustable airbrakes for optimal fine-tuning according to your setup.

  • 1 short 3.80 mm airbrake (optimal for 2J and 3J~ or higher).
  • 1 long 3.80 mm airbrake (optimal for 2J~ or lower).

A High Joule (shiny) piston head is included for higher joule output and a lighter bolt pull.
Use lubricant for perfect results; we recommend motor oil, silicone grease, or similar. As a reference, a Rapax Lightpull Blue 2J+ spring delivers 2.2–2.3~ joules in an SRS with a Stalker SRS cylinder and a 420 mm inner barrel. The original cylinder will produce fewer joules. Results may vary depending on the cylinder used.

Golden installation rules

  • Always apply a drop of oil or silicone grease to the edge of the head to achieve optimal joules.
  • For 2.3J setups, we recommend starting with the short airbrake and fully unscrewing it.
  • For 2.8J+ setups, we recommend starting with the short airbrake and fully screwing it in.
  • Always set your hop-up correctly for your desired BB weight and adjust it to shoot straight.
  • Higher joules = shorter airbrake
  • Lower joules = longer airbrake
  • Choose your airbrake and start low, then increase (unscrew) gradually until the setup becomes quiet.
  • When you begin losing joules, you know you are just past the perfect airbrake position; screw it back in slightly to regain joules and achieve the quietest setup.
  • Works best with the Stalker SRS cylinder

Good setups require adjustable airbrakes because too many parts in your rifle can change the piston acceleration speed. Spring power, bucking hardness, barrel length, piston weight, etc. We also recommend purchasing some spring guide spacers to fine-tune piston weight and spring joules.

Included in this kit:

  • 1x Stalker stainless steel Scorpion spring guide (with engraved Stalker logo)
  • 1x Dampening rubber to place inside the rear of the Stalker spring guide
  • 1x High Joule piston head (shiny)
  • 1x Extreme Silent Cup (matte finish)
  • 1x Aluminum piston head.
  • 1x Stainless steel piston head.
  • 5x Aluminum weights.
  • 4x Stainless steel weights.
  • Sear made of stainless steel (15 grams)
  • 2 Adjustable airbrakes (long and short)
  • 1x Nut to lock the airbrake setting
  • 10 O-rings for between the weights or stock to prevent the weights from loosening during play.
  • 2 spring guide O-rings for SRS A2 buttpad
  • Front and rear POM guide rings

Detailed information:

The Scorpion piston is a unique concept in which 6 weights form the actual body. Since 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 your cylinder volume and joule output, but makes cocking your SRS much shorter with each added weight—at the cost of joule output, which can be compensated with a stronger spring.

The piston comes with 9 body weights that are interchangeable to perfectly configure your SRS.

  • 5 black anodized aluminum body weights, each piece weighs: 3 grams
  • 4 polished stainless steel body weights, each piece weighs: 11 grams

Additionally, the piston also includes 2 head weight versions.

  • 1x Black anodized aluminum head weighing: 7 grams
  • 1x Polished stainless steel head weighing: 17 grams

List of 6-piece configurations:
(The fifth stainless steel mid-section weight is sold separately if you wish to use the full heavy steel configurations)

  • SRS Scorpion 62g (1 aluminum head, 5 aluminum mid sections)
  • SRS Scorpion 76g (1 aluminum head, 1 steel mid section, 4 aluminum mid sections)
  • SRS Scorpion 80g (1 steel head, 5 aluminum mid sections)
  • SRS Scorpion 89g (1 aluminum head, 2 steel mid sections, 3 aluminum mid sections)
  • SRS Scorpion 93g (1 steel head, 1 steel mid section, 4 aluminum mid sections)
  • SRS Scorpion 102g (1 aluminum head, 3 steel mid sections, 2 aluminum mid sections)
  • SRS Scorpion 107g (1 steel head, 2 steel mid sections, 3 aluminum mid sections)
  • SRS Scorpion 115g (1 aluminum head, 4 steel mid sections, 1 aluminum mid section)
  • SRS Scorpion 119g (1 steel head, 3 steel mid sections, 2 aluminum mid sections)
  • SRS Scorpion 128g (1 aluminum head, 5 steel mid sections)
  • SRS Scorpion 133g (1 steel head, 4 steel mid sections, 1 aluminum mid section)
  • SRS Scorpion 145g (1 steel head, 5 steel mid sections)
    This configuration requires a fifth stainless steel mid section, sold separately.

Both airbrakes are secured with a nut under the piston head against the head to keep them in place after adjustment. The adjustable airbrake is designed to fine-tune piston speed at the end of its travel to reduce cylinder air release time and minimize piston impact noise when it hits the cylinder head. A sorbo pad in the stock can still be used with this piston.

Basically, whether you like a plug-and-play piston or you are an expert who enjoys fine-tuning piston weights and airbrakes for maximum performance, the Stalker Scorpion is your best friend.

Fun with a late blooming omega
Format: Kindle
I like this book. The story is fun, cute, and sexy. There's just a little drama, some excellent, steamy scenes, and a fairly good relationship building storyline. I especially like how all the main characters are a bit older than the usual 20 somethings I tend to see in this kind of book. Having said that, I wish there were more descriptions of the places, as well as the food in the fancy restaurant. I enjoyed the cocktails at the club, so I missed that kind of detail when Gray took Madison on a dinner date. I also wish there had been more interaction between Lucas and Madison, and Lucas and Rian. It felt a bit lopsided, with a focus on Rian, Madison, and Gray. I wish it had been proofread - there are a lot of typos, but nothing too distracting.

Madison Deserved Better
Format: Kindle
Madison was a beta...except she wasn't any longer. She was a late presenting Omega. And she was struggling. She was tall and thin, not tiny and curvy. She was opinionated. She was everything an Omega was not. After suffering through her first heat, her friends took her to Ardor, a club where Omegas came to safely find Alphas. She's not expecting much but then she connects with a sexy beta. And when she meets his Alphas, they set her body on fire. Maybe, she's found her no-strings-attached heat pack. Maybe, she's found something more. I could not connect with the characters in this book, so their story never resonated with me. And there was no love story; there was sex. Grey made it clear from the beginning that he had a true love and it was his beta boy, Rian. He went so far as to reassure Rian “Say the word, I’ll never touch her again. Lucas can put the babies in her. I only need you, beta boy”. So, Madison was there for babies, no emotions needed. Nice. No, thank you. I want the Omega to be the center of their world, not an incubator. Lucas and Rian weren't any better. After her heat, they let her leave. Not one of them made her feel valued. No one gave her a reason to stay or even offered a cuddle. And the sex didn't even come across as mind-blowing. Madison deserved better.

Pretty Darn Good
Format: Kindle
So I’ve been on a omega kick and this definitely hit the spot. Madison was frustrating at times with how she acted towards Lucas, Gray, and Rian. It was like she said towards the end, she didn’t believe she deserved nice things. It would have been nice to hear from her best friends again. They kind of were there in the beginning and the gone except for mention of text messages received from them. I feel like her friends would have been great help in encouraging Madison to go with the pack and never give Brent another chance because he was toxic. I loved Rian. His personality was awesome. His humor. His ability to make Madison comfortable whenever she was feeling overwhelmed. And the fact he fell for her and she fell for him first. They are cute together. I do feel like Lucas was the odd man out though. Like Lucas didn’t develop as much of a relationship with Madison. I would have really liked to see more development in the relationship between them. It was also the same with him and Rian. There is really no relationship displayed. Most of the relationship being displayed is between Rian and Gray. Nevertheless, I loved reading about the dynamic that came to fruition during the entirety of this story. Madison finally got her happiness. And Brent finally got punched in the face. Everyone got exactly what they deserve.
