Product Descriptions:

SRS Scorpion Piston

The Stalker Scorpion piston has an extremely modular design, developed from scratch on my drawing table a long time ago. It includes all the options players could want for their SRS piston. It features a unique concept where six weights form the body itself. As the piston is made up of these weights, it is also possible to extend it with additional weights (short stroke), which reduces the cylinder volume and joule output.

Fluted Teflon Cylinder

This cylinder is a fluted Teflon version of a standard cylinder and gives your SRS A1 or A2 an aggressive look. The inner coating is applied using a cold treatment process, allowing the cylinder to retain its straight shape—something that is often not the case with heat-treated cylinders. Not only does your SRS get an aesthetic upgrade, but the special inner coating also improves energy transfer with pistons, potentially increasing joule output if your piston has a properly sized cup.

  • This cylinder is fully compatible with both Silverback SRS A1 and A2 receivers.
  • The cylinder thread works with both A1 and A2 bolt handles.
  • This cylinder is compatible with aftermarket pistons.

Rapax 3J+ RMS Spring

The Rapax Modular Spring (RMS) series is manufactured to the same high-quality standards as the Light Pull series. Built for durability and performance, these springs are designed to provide the best sniper experience. Compared to the Light Pull series, the RMS springs are considerably shorter, have a slightly heavier pull, and offer quieter shots. Additionally, RMS springs are electrically coated to prevent rust, ensuring smoother operation on the spring guide.

Excellent room divider
Color: Black, Size: 8 Panel
I have three of these from this company! 2 of them are 6 panel and one 8 panel (this one). A+ quality and wonderful with privacy. I have this on my screened in balcony and it withstands the wind pretty well. Fits right behind my giant plant pots. No assembly needed and it was long enough to cover the entire screened area. No more nosy neighbors! Great for Condos! Woohoo!

Great Divider
Comes assembled. It is heavy, but fairly easy to move and use. I’m 5’4, 110 and I can do it myself. It’s thick, it’s tall, it looks good, not sloppy or cheap. Doesn’t smell. Great room divider. We use it for our office between our desks.

Good purchase
Color: White, Size: 8 Panel
I bought this in white for use in a finished basement to hide equipment on the wall and create a nice space to place a bed. Because it doesn’t need to be moved and the room is temperature controlled, I expect it to last for a long time. The screen is pretty and I like that the woven material is not easily breakable. I’m pleased with the purchase.
