cylinder is a modified, lighter version of the standard model, weighing only 49 grams. This significantly lighter version features a Teflon coating and only two sliding contact points with the receiver, making your SRS A1 or A2 look super cool. The internal coating is a cold treatment, preserving the cylinder's straightness—unlike thermally treated cylinders. Your SRS not only gains proper performance, but the internal coating enhances energy transfer to the piston, potentially increasing your joules if your piston has the correct cup size.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eCompatibility:\u003c\/strong\u003e\u003c\/p\u003e\n\u003cul\u003e\n\u003cli\u003e\u003cstrong\u003eFully compatible with Silverback SRS A1 and A2 receivers\u003c\/strong\u003e\u003c\/li\u003e\n\u003cli\u003e\u003cstrong\u003eCylinder thread works with both A1 and A2 bolt handles\u003c\/strong\u003e\u003c\/li\u003e\n\u003cli\u003e\u003cstrong\u003eCompatible with aftermarket pistons\u003c\/strong\u003e\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cp\u003e\u003cstrong\u003eInstallation Instructions:\u003c\/strong\u003e\u003c\/p\u003e\n\u003cul\u003e\n\u003cli\u003e\u003cstrong\u003eLubricate the piston cup with PTFE Dry Spray or a drop of silicone oil before use with the new cylinder\u003c\/strong\u003e\u003c\/li\u003e\n\u003cli\u003e\u003cstrong\u003eLubricate the outer surface of the cylinder with PTFE Dry Spray before use\u003c\/strong\u003e\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cp\u003eYou can follow all my live streams, photos, and info on my Instagram, Facebook, or YouTube channels here:\u003c\/p\u003e\n\u003cp\u003e3 Versions.\u003c\/p\u003e\n\u003cp\u003eFlutted,\u003c\/p\u003e\n\u003cp\u003eGold\u003c\/p\u003e\n\u003cp\u003eLightweight\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 noreferrer\"\u003ehttps:\/\/www.youtube.com\/channel\/UCWsBiSHlu-lbcnGQWAkeJWQ\u003c\/a\u003e\u003cb\u003e \u003c\/b\u003e\u003c\/p\u003e\n\u003cp\u003e \u003c\/p\u003e\n\u003cdiv\u003e2.11.0.0\u003c\/div\u003e","brand":"STALKER","offers":[{"title":"Default Title","offer_id":52553374728533,"sku":"SP-STAL-23","price":39.95,"currency_code":"EUR","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/1024\/3607\/7909\/files\/stalker-lightweight-cylinder-photo3_6aab67cb-3066-4689-9bbd-3b85e6dbe842.png?v=1771965851"},{"product_id":"silverback-srs-cylinder-stainless-steel","title":"SRS Twisted Stainless Steel Cylinder","description":"\u003cp\u003eSRS Twisted Stainless Steel Cylinder\u003c\/p\u003e\u003cdiv\u003e2.11.0.0\u003c\/div\u003e","brand":"Silverback","offers":[{"title":"Default Title","offer_id":52585448767829,"sku":"SP-SBA-CYL-04","price":66.35,"currency_code":"EUR","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/1024\/3607\/7909\/files\/sba-cyl-04-4-scaled_1746b570-8e3e-475c-818f-0b4845362521.jpg?v=1771330283"}],"url":"https:\/\/www.skirmshop.es\/collections\/srs-pistons-cylinders.oembed","provider":"Skirmshop Spain","version":"1.0","type":"link"}
