SRS Scorpion Piston

The Stalker Scorpion piston features an extremely modular design that was developed from scratch. It offers every option players could want for their SRS piston. This unique concept uses 6 weights that form the piston body itself. Since the piston is made up of these weights, it can be extended with additional weights (short-stroke), which reduces cylinder volume and joule output.

Morpheus 570MM Inner Barrel

The Morpheus Hybrid Barrel is made from highly durable SUS304 stainless steel and features a Dualbore tapered end-crowning to improve range and accuracy.

We use stronger and more durable seamless SUS304 steel to raise the standard. Most brands use SUS303 seamed steel because it is easier to machine. SUS303 stainless steel has reduced corrosion resistance due to its composition, as it is optimized for machinability. SUS304 steel is harder to machine but offers superior durability and excellent corrosion resistance.

Fluted Teflon Cylinder

This cylinder is a Teflon fluted version of a standard cylinder, giving your SRS A1 or A2 an outstanding look. The inner coating is applied using a cold treatment process, allowing the cylinder to retain its perfectly straight shape—unlike many heat-treated cylinders. In addition to enhanced aesthetics, the special inner coating improves energy transfer with the piston, potentially increasing joule output if your piston has a properly sized cup.

• Fully compatible with both Silverback SRS A1 and A2 receivers
• Compatible with both A1 and A2 bolt handles
• Works with aftermarket pistons

Rapax 2J+ RMS Spring

The Rapax Modular Spring (RMS) series is manufactured to the same high-quality standards as the Light Pull series. Designed for durability and performance, these springs provide an exceptional sniper experience. Compared to the Light Pull series, RMS springs are considerably shorter, have a slightly heavier pull, and deliver quieter shots. They are also electrically coated to prevent rust and ensure smoother operation on the spring guide.
