Scorpion Piston SRS
The Stalker Scorpion piston features an extremely modular design that was created from scratch on my drawing board a long time ago. It offers every option players could want for their SRS piston. It is a unique concept in which 6 weights form the body itself, and since 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 your cylinder volume and joules.
Morpheus 420MM 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 most durable and resistant seamless SUS304 steel because we wanted to raise the standard a bit. Most brands use SUS303 steel because it is easier to machine. The corrosion resistance of SUS303 stainless steel is weakened due to its composition, as it is specialized for machining. The SUS304 steel we use is more difficult to machine but 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, so the cylinder retains its straight shape, which is often not the case with heat-treated cylinders. The cylinder also features a special internal coating that provides better energy transfer with pistons, which could also increase your joules 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 works with various aftermarket pistons.
Rapax 2.8J
Galvanized to prevent rust, reduce friction, and provide a longer service life compared to other springs
