The new Stalker Scorpion piston kit for the VSR-10!

Key features:

  • Modular piston with adjustable weight (65 to 148 grams)
  • Reduces noise in your VSR-10
  • Improves joule/FPS consistency
  • Adjustable air brakes with dual O-ring cuts for optimal tuning
  • Short-stroke option for faster reloads (at the cost of some joules)
  • Includes a 3mm thick, 40D hardness shock pad to prevent piston impact noise against the VSR cylinder head
  • Shock pads in various hardnesses and sizes available (see related products)
  • Optimized to work with 9mm springs and Stalker spring guides.

The piston comes with two adjustable air brakes (3.80 mm) for optimal tuning based on your setup.

  • 1 short air brake (3.80 mm) — optimal for 2J and 3J+ builds.
  • 1 long air brake (3.80 mm) — optimal for 2J or lower builds.

Airbrake <> Cylinder Head Compatibility:

  • Action Army cylinder head = 3.80 mm airbrake
  • TM cylinder head = 3.80 mm airbrake
  • Laylax cylinder head = 3.80 mm airbrake
  • SSG-10 cylinder head = 4.40 mm airbrake
  • Other cylinder heads = measure inner nozzle diameter and select optimal airbrake

3.80 mm Airbrake for Scorpion Pistons (SKU: ST-102)

4.00 mm Airbrake for Scorpion Pistons (SKU: ST-101)

4.40 mm Airbrake for Scorpion Pistons (SKU: ST-103)

The new piston design features a slightly modified piston cup for optimal performance in VSR-10 cylinders. This cup performs reliably from 1J to 4J+.

Installation Golden Rules:

  • Always apply a drop of silicone oil or grease on the cup edge for optimal joules.
  • For 2.3J setups, start with the short airbrake fully unscrewed.
  • For 2.8J and above, start with the short airbrake fully screwed in.
  • Always properly adjust your hop-up to your BB weight and ensure straight shooting.
  • Higher joules = shorter airbrake.
  • Lower joules = longer airbrake.
  • Start with the airbrake in a low position and gradually unscrew it until the setup is quiet.
  • When you start losing joules, you’ve passed the optimal position — screw it back in slightly to regain joules and achieve the quietest setup.

Optimal setups require adjustable airbrakes because many components affect piston acceleration speed — such as BB weight, spring strength, hop-up rubber hardness, barrel length, and piston weight. We also recommend purchasing spring guide spacers to fine-tune piston weight and joule output.

Kit includes:

  • 1x Stalker Scorpion 9mm spring guide (engraved with Stalker logo)
  • 1x 3mm thick, 40D hardness green shock pad (cylinder head not included)
  • 1x Piston cup
  • 1x Aluminum piston head
  • 1x C...

Not for heavy chewers!
Theme: Animals, Size: Medium
Didn't hold up well - but realized I didn't read that it was for "light chewers." Otherwise, cute design.

Good for Chewers
Theme: Football, Size: Large
Dogs love it, they been chewing on it and it's like new. Also I put treats inside and they really like that. I have a small pit mix and a puppy shepherd husky mutt. They play tug of war with it and it's holding up really good.

Great inside toy
Theme: Football, Size: Large
Our Rottie loves these! I wanted something like the Jolly Ball but that is soft for inside the house. She's had a lot of fun with this, picking it up, tossing it, playing soccer, etc.

A BIG hit with my BIG dog!
Theme: Football, Size: Large
My Great Dane/Boxer mix LOVES this toy. She is over 100 lbs and very strong. She got a hold of my son's real football last year and after she made the initial holes and deflated it we just let her have it. She completely ripped it to shreds in about 7 months but had such a blast tossing it around and galloping around the yard with it, I knew I had to replace it with something of the same shape but hopefully more durable. This is it! She really adores this. We play catch and tug with it and it seems like it's going to last a really long time. The rubber is flexible but strong. I'll try to get a picture of her with it and load it. I highly recommend this toy. We ordered the Large size, by the way. :-) 2-6-2015 - Update: I am just now ordering a new one. For nearly 4 years, the old one has been kept outside in the rain, sun, snow, and ice. She still loves to grab it, shake it, throw it up in the air and play tug with whenever she's outside. The rubber is just now starting to crack so it's time for a new one.

Holding up very well, favorite
Theme: Football, Size: Large, Theme: Football, Size: Large
A few weeks ago I ordered three dog toys for my dogs. I have a German shepherd, Lab mix and a medium mix. The latter boy is the biggest destroyer in our family, he chewed pieces of a black Kong. I did not really have high hopes for this football shaped toy with holes, but it is holding up beyond my expectations. You can see some teeth marks, but they are not chewing it up (yet?). They love to play tug with this, kick it around by themselves, or lie down with it and chew on it. I like it because it is a soft rubber and doesn't make so much noise when they throw it around on my hard flooring. For the price, they are definitely getting a whole lot of fun out of it. Edit: Now, more than a month later, my dog managed to get a small piece off after a heavy chew session. After that first piece apparently it is easy to get more off, and he wants to swallow it so the ball is in the trash.
