It includes all the options players could want for their SRS piston. It features a unique concept where six weights form the body itself. As the piston is made up of these weights, it is also possible to extend it with additional weights (short stroke), which reduces the cylinder volume and joule output.\u003c\/p\u003e\n\u003cp\u003e\u003cem\u003e\u003cstrong\u003eFluted Teflon Cylinder\u003c\/strong\u003e\u003c\/em\u003e\u003c\/p\u003e\n\u003cp\u003e\u003cem\u003eThis cylinder is a fluted Teflon version of a standard cylinder and gives your SRS A1 or A2 an aggressive look. The inner coating is applied using a cold treatment process, allowing the cylinder to retain its straight shape—something that is often not the case with heat-treated cylinders. Not only does your SRS get an aesthetic upgrade, but the special inner coating also improves energy transfer with pistons, potentially increasing joule output if your piston has a properly sized cup.\u003c\/em\u003e\u003c\/p\u003e\n\u003cul\u003e\n\u003cli\u003eThis cylinder is fully compatible with both Silverback SRS A1 and A2 receivers.\u003c\/li\u003e\n\u003cli\u003eThe cylinder thread works with both A1 and A2 bolt handles.\u003c\/li\u003e\n\u003cli\u003eThis cylinder is compatible with aftermarket pistons.\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cp\u003e\u003cem\u003e\u003cstrong\u003eRapax 3J+ RMS Spring\u003c\/strong\u003e\u003c\/em\u003e\u003c\/p\u003e\n\u003cp\u003eThe Rapax Modular Spring (RMS) series is manufactured to the same high-quality standards as the Light Pull series. Built for durability and performance, these springs are designed to provide the best sniper experience. Compared to the Light Pull series, the RMS springs are considerably shorter, have a slightly heavier pull, and offer quieter shots. Additionally, RMS springs are electrically coated to prevent rust, ensuring smoother operation on the spring guide.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003e\u003cu\u003eIf you have any issues or questions about this or other Stalker products, please visit our Stalker Owners Group on Facebook here: \u003ca href=\"https:\/\/www.facebook.com\/groups\/329589544772075\/\"\u003ehttps:\/\/www.facebook.com\/groups\/329589544772075\/\u003c\/a\u003e\u003c\/u\u003e\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp\u003eYou can follow all my live streams, photos, and updates on Instagram, Facebook, or YouTube here:\u003cbr\u003e\u003cbr\u003eFacebook: \u003ca href=\"https:\/\/www.facebook.com\/StalkerAirsoftDesigns\/\" target=\"_blank\" rel=\"noreferrer noopener\"\u003ehttps:\/\/www.facebook.com\/StalkerAirsoftDesigns\/\u003c\/a\u003e\u003cbr\u003eInstagram: \u003ca href=\"https:\/\/www.instagram.com\/stalkerairsoftdesigns\/\" target=\"_blank\" rel=\"noreferrer noopener\"\u003ehttps:\/\/www.instagram.com\/stalkerairsoftdesigns\/\u003c\/a\u003e\u003cbr\u003eYouTube: \u003ca href=\"https:\/\/www.youtube.com\/channel\/UCWsBiSHlu-lbcnGQWAkeJWQ\" target=\"_blank\" rel=\"noopener\"\u003ehttps:\/\/www.youtube.com\/channel\/UCWsBiSHlu-lbcnGQWAkeJWQ\u003c\/a\u003e\u003c\/p\u003e\n\u003cp\u003e\u003cb\u003eFor more information about Stalker products, tech \u0026amp; crafting guides, please visit: \u003ca href=\"http:\/\/www.stalkerairsoft.com\/\" target=\"_blank\" rel=\"noopener\"\u003ewww.stalkerairsoft.com\u003c\/a\u003e\u003c\/b\u003e\u003c\/p\u003e","brand":"STALKER","offers":[{"title":"Default Title","offer_id":52552018493781,"sku":"SP-STAL-179","price":119.0,"currency_code":"GBP","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/1024\/3607\/7909\/files\/srs-start-kit-3j_de24d00e-da74-4685-a4ea-a76be3e5379a.jpg?v=1771967662","url":"https:\/\/www.skirmshop.es\/en-gb\/products\/stalker-starter-srs-upgrade-kit-3-0-3-5-joule","provider":"Skirmshop Spain","version":"1.0","type":"link"}
