It has all the options people might desire for their SRS piston. It’s a unique concept where 6 weights form the body itself, and as the piston is formed by 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 the joules.\nMorpheus 420MM Inner Barrel The Morpheus hybrid barrel is made of very durable SUS304 stainless steel and has a conical crown (Dualbore) to enhance its range and accuracy.\nWe use the most durable and resistant seamless SUS304 steel because we wanted to slightly improve the game. 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 in machining; therefore, the SUS304 steel we use is harder to machine but more durable and has wonderful corrosion resistance.\nTeflon-Cylinder This cylinder is a Teflon version of a normal cylinder. The internal coating treatment of the cylinder is a cold treatment, so the cylinder retains its straight shape, which is often not the case with thermally treated cylinders. The cylinder also has a special internal coating that provides better energy transfer with pistons, which could also increase your joules if your piston has the proper size cup.\nThis cylinder is fully compatible with Silverback SRS A1 and A2 receivers.\nThis cylindrical thread works on the A1 and A2 bolt handles.\nThis cylinder works with various market pistons.\nRapax 2.8J Galvanized to prevent rusting, reduce friction, and provide you with a prolonged usage period compared to other springs.\n*The box is for promotional purposes only and is not included*\nYou can follow us on Instagram, Facebook, or write to us at our email:\nFacebook: https:\/\/www.facebook.com\/StalkerAirsoftDesigns\/ Instagram: https:\/\/www.instagram.com\/stalkerairsoftdesigns\/ Youtube: https:\/\/www.youtube.com\/channel\/UCWsBiSHlu-lbcnGQWAkeJWQ Email: info@skirmshop.es\nFor more information about Stalker Products, Tech \u0026amp; Crafting Guides Please Visit: www.stalkerairsoft.com.
