STALKER:
I am pleased to announce the new Stalker Scorpion piston. A piston that has been in development since September 2019. I have had this piston in prototype stage for more than enough time and shared prototype versions within our test panel with amazing results. The parts have been precisely tuned to deliver the best possible performance for your SRS A1 or A2/M2.

The Stalker Scorpion piston features an extremely modular design created from scratch on my drawing board a long time ago. It includes every option people could wish for in their SRS piston. It is a unique concept where 6 weights form the actual body, and 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.

The 6-piece configuration allows for 12 different setups. By extending the piston with an additional weight, you gain access to 12 additional configuration options.

Here is a list of the 6-piece configurations:

SRS Scorpion 62g (1 aluminum head, 5 aluminum intermediate sections)
SRS Scorpion 76g (1 aluminum head, 1 steel intermediate section, 4 aluminum intermediate sections)
SRS Scorpion 80g (1 steel head, 5 aluminum intermediate sections)
SRS Scorpion 89g (1 aluminum head, 2 steel intermediate sections, 3 aluminum intermediate sections)
SRS Scorpion 93g (1 steel head, 1 steel intermediate section, 4 aluminum intermediate sections)
SRS Scorpion 102g (1 aluminum head, 3 steel intermediate sections, 2 aluminum intermediate sections)
SRS Scorpion 107g (1 steel head, 2 steel intermediate sections, 3 aluminum intermediate sections)
SRS Scorpion 119g (1 steel head, 3 steel intermediate sections, 2 aluminum intermediate sections)




Below I will explain the features of this piston.

The piston cups are made of durable, high-quality rubber and have been tested and tuned to deliver the best performance with cylinders currently available on the market. The piston cups are available in two versions.

Black Cup

Zero loading friction.
No thumb seal block.
Higher joule output.
Fast cocking (lighter pull).
Works best with the Stinger Tapered Brass air brake
Brown Cup

Medium sized.
Low friction.
100% thumb seal block.
Lower joule output than the black cup
Works best with brass air brakes.
A drop of oil on the edge of the cup is recommended.
The piston comes with various body weights (depending on the product edition), which are interchangeable to perfectly configure your SRS.

Available in black anodized aluminum, each piece weighs: 7 grams
Available in gold-coated polished steel, each piece weighs: 21 grams
Additionally, the piston head is also available in these versions.

Black anodized aluminum, each head weighs: 8 grams
Gold-coated polished steel, each head weighs: 24 grams
This allows you to configure the piston between approximately 65 to 148 grams (depending on the air brake), enabling you to tune it for any desired joule output.


In addition, the piston comes with 1 adjustable air brake.

1x Adjustable Air Brake made of brass.

This is a thick brass air brake, not tapered. This air brake provides the most "direct" braking effect — once the air brake enters the nozzle, the piston immediately begins to slow down.

Other included parts:

Sear End Cap made of stainless steel.
10 O-rings for placement between the weights or stock to prevent the weights from loosening during gameplay.
Front guide ring made of POM.
Receiver guide ring made of POM.
9mm laser-engraved Stalker spring guide with top cut for the adjustable air brake.
Soft bumper pad that fits onto the spring guide to reduce impact. (Hard protective pad available separately; item code: ST-050)
2 O-rings for the spring guide fitting the A1 stock.
2 O-rings for the spring guide fitting the A2/M2 stock.
The Scorpion piston inlet size has been optimized to work best with Rapax and Silverback springs; it may also work well with other brands provided they have the same diameter as the springs mentioned above.

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

Best Pillow Ever
Color: Blue-ice Plus, Size: Queen(Pack of 2)
Best pillow ever. Although it still gets "hot", it does take longer to get "hot". I love this pillow. I was buying a new pillow almost every 3 months. Other pillows would either remain rock hard or go flat. I was concerned at first when reading the description as I though the memory foam would be big pieces. They are soft fluffy pieces. I had to remove almost half of the foam to get the pillow to what works for me. I have not had to put any filler back in. Maybe in a couple of more months I may have to put a bit more in, but it is holding it's shape and not going flat. I do fluff it every night. This helps. I am a stomach sleeper. I have bought the expensive purple pillow and hated it so much I gave it to my daughter. This QUTOOL Pillow is the best! I bought a 2 pack. Have not used the other pillow yet, but I feel I may actually go years for once without having to buy a pillow as I have the 2nd one set aside if the first one gets to a point in need replacement. I have bought Dollar Store pillows. I have bought $300 pillows. None of them even come close to this pillow and the way you can adjust this pillow for you. The pillows came in a white mesh like bag. I keep all the unused "stuffing" in this bag. I have it hanging in my closet and I just fluff the bag once a month to keep the filling fresh so it is ready if and when I need it. Coming from someone who has trouble staying asleep, neck issues, a stomach sleeper who hate those flat pillows manufacturers think stomach sleepers like but actually hate, buy this pillow. Just buy it. Best Pillow for a picky person like me. Buy 2 or more so if you have to stay at a hotel, you can take your own pillow.

Foam Mattress NEEDs Foam Pillows
Color: Blue-ice Plus, Size: King(Pack of 2), Color: Blue-ice Plus, Size: King(Pack of 2)
10 stars!! Quality foam, structure & price. Best bang for my buck.    HRV, readiness & total sleep score metrics increased drastically this week.  See screenshot :) Support: Molds and cushions every crevice under my neck and above shoulders. So comfy  Size: Adjustable loft but king length is perfect to hug and rest your head.  Love love love. The 1st 2 nights were uncomfortable with pillow as is, first night I was up at 3am half asleep pulling foam out but wasn't enough. The second night at 2am I pulled out more stuffing. I was getting frustrated..  my Oura ring showed both nights I was awake every hour.  Not good.  Before the 3rd night I pulled enough to fill the bag the 2 pillows arrived in. Boom -8hrs sleep and for the first time ii years I achieved 17% Deep sleep.  Huge. Weight: Perfect weight with adjustment. Squishy and molds to b the contour of my neck and shoulders Softness: Like the baby bear.. just right.   Comfort: Very comfortable after removing 30% foam in both pillows. I actually now have enough to make a 3rd pillow, replace old foam, or adjust OGs, Still to early to measure.  If you have a foam mattress that contours your body but not your head you'll end up with neck and/or back pain from head being elevated- not sinking/molding the body into a foam mattress.

These are not sized correctly - beware
Color: Blue-ice Plus, Size: King(Pack of 2), Color: Blue-ice Plus, Size: King(Pack of 2)
Edit: I was going to return these pillows but the seller contacted me and offered a full refund due to the size issue without having to send the pillows back. I am happy with this and happy to keep them on a spare queen size bed as they really are nice pillows. Just the wrong size. pros: they are a nice pillow and the cooling feature is really great, and you can adjust to your liking cons: absolutely wrong size. Ordered King, tag says king, all measurements on listing and tag say 20x36, in reality they are more like 20x30. Definitely Queen pillows being sold as King. I did not see any reviews at first about size issues but after I got these and did a search it does look like others have had the same problem. A shame, would have given them a great review if they were the correct size
