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.

Great quality. Easy to clean. Nice appearance.
Color: Red, Size: 4.3-Quart
Solid, heavy pot for cooking and baking. I bought it mainly for making soups, stews and breads. I have only tried soups thus far. The pot cleaned up very easily. The bottom of the pot heated uniformly. Nothing was stuck to the pot when I was simmering on the glass top stove. I have not had the chance to bake yet, but seeing how evenly it held heat while cooking, I am thinking this will be perfect. I bought the red color. It gives a nice pop of color in my kitchen. This pot will probably last me a long time. I would buy one if I needed a replacement, or a gift for someone.

Great quality for price after 3 years of use
Color: Matte Navy, Size: 6-Quart, Color: Matte Navy, Size: 6-Quart
I’m 3.5 years in and use it weekly. So far it’s been a great product especially for the price. We are really into soups, roast, and I bake bread a lot. This thing is amazing and a great quality. It’s easy to clean, does great in the oven, and stands up great to constant use. I only have a small amount of staining at the bottom, and a couple scratches from metal utensils. The lid is solid and the handle is really secure still, which is a problem I’ve had with other brands I’ve tried.

Quality product
Color: Navy, Size: 6-Quart
I absolutely LOVE my Dutch oven! The reduced cooking time for certain cuts of meat for stews, pot roast, etc., is a definite game changer!! The meat comes out so juicy and tender. I made curry and did the "burning" of the curry and was hesitant because I didn't want the pot to be stained. There were no stains left at all. I've used it numerous times since purchasing and it still looks new. It's very durable and the color is beautiful. If you're looking for a functional, quality, and durable Dutch oven without breaking the bank, this is it! I highly recommend.

Nothing Exceptional but Gets the Job Done
Color: Blue, Size: 4.3-Quart, Color: Blue, Size: 4.3-Quart
I’ve owned this 4.5 Qt. Amazon Enameled Cast Iron Dutch Oven for almost two months and have used it three times to date. Upon arrival and at first glance, the gradient blue color is beautiful and super glossy; most importantly, the pot is heavy for its size - as it should be. It looks exactly like the product pictures, with a globular shape than square shape as others. Unfortunately, I also noticed that there was one pin hole and two tiny uneven protrusions on the enamel inside the pot. I own three other enameled cast iron cookware from two other brands (photos attached for size comparison) and performance wise, this cast iron by Amazon performs equally to them. The pot isn’t exceptional or special but it gets the job done. Other than the pin holes and protrusions, I have no complaints. This isn’t my first rodeo so when heating up the pot and while cooking, I have zero issues. I am starting the pan off at 4-Stars and will update my review as time progresses, or if I have any major issues with its durability or performance in subsequent months. For the amateur home cook, or for anyone who is new to cast iron cooking, below I’ve included tips that you may find useful while using this or any other enameled cast iron cookware. ================================ Regarding the 3 Photos and 1 video I've Attached: (Note: all photos were taken with an iPhone under kitchen lights during the evening. Photos have not been edited nor enhanced.) Photo 1: Size comparison of this Amazon Enameled Cast Iron Dutch Oven compared to three other enameled cast iron cookware that I own from two other brands. From left to right: 7 qt. Tramontina, 4.5 qt. Amazon, 3 qt. Lodge 4 qt. Tramontina. Photos 2 and 3: fresh produce shown next to 4.5qt Amazon Dutch Oven for color and size contrast. Video: 4.5 qt. Amazon Enameled Cast Iron Dutch Oven on gas stove over medium heat, with food cooking. ================================ TIPS THAT YOU MAY FIND USEFUL While Using your cast iron dutch oven: (Note: I included these similar tips in my review of a different enameled cast iron pot from a different brand. My tips can apply to all enameled cast iron cookware) 1. If you find that you have issues with food sticking, it could be that you are not heating up your cast iron pot properly to prevent undue hot spots. I heat my pot up gradually starting at low, then medium, then high heat. After my pot is very hot is when I add my fat/cooking oil. As the oil is heating up in the pot, I lift it and swirl the oil around to coat all sides of the pot that will come in contact with food. 2. Take into consideration the temperature of the items you are adding to your heated pot. As a general rule for cooking: when ever possible, ensure that the items you are adding to a hot pot are at room temperature, rather than ice cold from the fridge; this will assist with even cooking. 3. Also, get comfortable with adjusting your heat by lowering and raising it based on what you’ve added to the pot. In general, you will need more heat at the beginning of the cooking process, and less heat towards the end. If you cook by recipe, I highly recommend that you read all the steps ahead before starting, so that you become familiarized with all the procedures, allowing you to maneuver accordingly when you start cooking. 4. At the exception of searing meat to achieve a brown crust, deep frying, or when caramelizing onions, you should be stirring your pot (I recommend using a wooden spoon) every few minutes when cooking in cast iron that is placed over high heat. If you are braising on the stove at low heat versus braising in the oven, the frequency of your stirring will need to be adjusted. No matter how you’re cooking though, a watchful eye on the pot plus stirring, should both be a habit not an afterthought. 5. For all cooking vessels in general but especially for cast iron: after cooking, allow your pot to cool down completely before cleaning. NEVER immerse a hot cast iron pot into cold water, nor pour cold dish water into hot pot. You risk not only being scald by dangerous steam, but you also risk weakening the enamel, therefore lessening the durability of your pots over time. 6. This cookware and others like it from Tramontina and Lodge are economical and if used correctly, will perform well for most cooking; if used correctly, they should also last for years. Nonetheless, if you can afford it, authentic enameled cast iron cookware made in France by Le Creuset is the best way to go. Le Creuset is the gold standard in cast iron cookware and their quality is second to none. I definitely recommend this Amazon dutch oven but if you can afford to splurge, Le Creuset's reputation is stellar. As a professional chef, I've used them in high end kitchens and their quality and performance is premier.
