It has all the options anyone 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 joule creep.\n\n\u003cstrong\u003eTeflon Cylinder\u003c\/strong\u003e\n\nThis cylinder is a Teflon version of a standard cylinder. The inner cylinder 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 improves in appearance, but the cylinder also features a special inner coating that provides better energy transfer with pistons, which can also increase your joules if your piston has a properly sized cup.\n\nThis cylinder is fully compatible with Silverback SRS A1 and A2 receivers.\nThis cylinder thread works with A1 and A2 bolt handles.\nThis cylinder works with other pistons.\n\nRapax 2.8J Spring.\n\nBuilt with durability and quality to give you the best sniper experience.\n\nIf you have any issues or questions about this or other Stalker products, visit our Stalker Facebook group here: https:\/\/www.facebook.com\/groups\/329589544772075\/\n\nYou can follow all my live streams, photos, and updates on my Instagram, Facebook, or YouTube channels here:\n\nFacebook: https:\/\/www.facebook.com\/StalkerAirsoftDesigns\/\nInstagram: https:\/\/www.instagram.com\/stalkerairsoftdesigns\/\nYoutube: https:\/\/www.youtube.com\/channel\/UCWsBiSHlu-lbcnGQWAkeJWQ\n\nFor more information about Stalker products, tech guides, and build guides, visit: www.stalkerairsoft.com\u003c\/span\u003e\u003c\/pre\u003e","brand":"Skirmshop Spain","offers":[{"title":"Default Title","offer_id":52551208829269,"sku":"SP-xxxx","price":164.99,"currency_code":"EUR","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/1024\/3607\/7909\/files\/descarga-6_5a531552-5f4b-4c84-aeb1-68bb2f562e6d.jpg?v=1771968906"},{"product_id":"rapax-rms-4-joule-spring-srs-ssg-vsr","title":"RMS 4+ Joule Spring (SRS\/SSG\/VSR)","description":"\u003ch1\u003eRMS 2+\/3+\/4+ J Spring - SRS \/ SSG \/ VSR (APS2 standard, 13 mm spring)\u003c\/h1\u003e\n\u003cp\u003eRMS stands for \u003cstrong\u003eRapax Modular Spring\u003c\/strong\u003e.\u003c\/p\u003e\n\u003cp\u003eThe Rapax Modular Spring series is manufactured to the same quality standards as the Light Pull series springs.
