Use a small amount of oil-based lubricant for optimal performance; we recommend motor oil silicone grease or similar.\u003c\/p\u003e\n\u003cp\u003eAs a reference, a 2J+ Blue spring delivers ~3J on an SRS with Stalker SRS cylinder + 420mm inner barrel.\u003c\/p\u003e\n\u003cp\u003eThe original cylinder will produce slightly fewer joules. Results may vary depending on the cylinder used.\u003c\/p\u003e\n\u003cp\u003eWe also offer an extremely quiet piston cup that reduces joules to near standard spring output, but is easier to make ultra-quiet.\u003c\/p\u003e\n\u003cul\u003e\n\u003cli\u003eZero loading friction.\u003c\/li\u003e\n\u003cli\u003eThumb-sealed.\u003c\/li\u003e\n\u003cli\u003eHigh joule output.\u003c\/li\u003e\n\u003cli\u003eFast cocking (lighter pull) due to a looser spring that still delivers significantly more joules.\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cp\u003eYou can follow all my live streams, photos, and info on my YouTube, Facebook, or Instagram channels here:\u003c\/p\u003e\n\u003cp\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\u003eFor more information on Stalker products and technical build guides, visit: \u003cb\u003e\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":52552470036821,"sku":"SP-STAL-55","price":11.0,"currency_code":"GBP","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/1024\/3607\/7909\/files\/blackcup1_5301afd1-32e2-49ed-a6e5-9af91d2a3210.jpg?v=1771966253","url":"https:\/\/www.skirmshop.es\/en-gb\/products\/stalker-scorpion-srs-tac41-high-joule-piston-head","provider":"Skirmshop Spain","version":"1.0","type":"link"}
