Product Description:

SRS Scorpion Piston

The Stalker Scorpion piston features an extremely modular design that was created from scratch on my drawing table a long time ago. It includes all the options players could want for their SRS piston. It is 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 the piston with additional weights (short stroke), which in turn reduces the volume of your cylinder and joule output.

Fluted Teflon Cylinder

This cylinder is a Teflon fluted version of a standard cylinder and makes your SRS A1 or A2 look outstanding. The inner coating treatment is a cold process, so the cylinder retains its straight shape, which is often not the case with heat-treated cylinders. Your SRS not only gets an aesthetic upgrade, but the cylinder also features a special inner coating that provides better energy transfer with pistons and may increase your joule output if your piston has a correctly sized cup.

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

Rapax 2J+ RMS Spring

The Rapax Modular Spring (RMS) series is manufactured to the same quality standards as the Light Pull series springs. Built for durability and performance, they are designed to provide the best sniper experience. Compared to the Light Pull series, 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.
