Scorpion Piston SRS

The Stalker Scorpion piston features an extremely modular design that was developed from scratch on my drawing board a long time ago. It offers all the options players could want for their SRS piston. It is a unique concept in which 6 weights form the piston body itself. Since the piston is built from these weights, it is also possible to extend it with additional weights (short-stroking), which in turn reduces cylinder volume and joules.

Morpheus 510MM Inner Barrel

The Morpheus hybrid barrel is made from highly durable SUS304 stainless steel and features a conical crown (Dualbore) to improve range and accuracy.

We use the more durable and resistant seamless SUS304 steel because we wanted to raise the standard. Most brands use SUS303 steel because it is easier to machine. The corrosion resistance of SUS303 stainless steel is reduced due to its composition, as it is specialized for machining. The SUS304 steel we use is more difficult to machine but far more durable and offers excellent corrosion resistance.

Teflon Cylinder

This cylinder is a Teflon-coated version of a standard cylinder. The internal coating treatment is a cold process, allowing the cylinder to retain its straight shape, which is often not the case with heat-treated cylinders. The cylinder also features a special internal coating that provides improved energy transfer with pistons, which may increase joule output if your piston has a properly sized cup.

This cylinder is fully compatible with Silverback SRS A1 and A2 receivers.

This cylinder thread works with both A1 and A2 bolt handles.

This cylinder is compatible with various aftermarket pistons.

Rapax 2.8J

Galvanized to prevent oxidation, reduce friction, and provide extended service life compared to other springs.
