This edition is a prebuilt Scorpion Piston, assembled at 100 grams with an adjustable airbrake to upgrade your SRS.\u003c\/p\u003e\n\u003cp\u003eThis edition will make your SRS quieter, provide smoother piston movement, and improve FPS consistency.\u003c\/p\u003e\n\u003cp\u003eAt 100 grams, this piston works perfectly with inner barrels from 310 mm to 510 mm. You will not need to adjust the piston weight if you are shooting between 2 and 3 joules with these barrels. For higher or lower joule outputs, or shorter or longer inner barrels, we suggest getting the Ultimate Edition for greater adjustability.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eThe difference between this version and the Ultimate Edition is that the Ultimate Edition offers greater weight adjustability (both higher and lower) and includes additional weights and an airbrake.

Since the piston is made up of these weights, it is also possible to extend it with additional weights (short-stroke configuration), which reduces cylinder volume and joule output, but significantly shortens the bolt pull of your SRS with each added weight. The reduced joule output can be compensated with a stronger spring or the High Joule cup.\u003c\/p\u003e\n\u003cp\u003eBasically, whether you prefer a plug-and-play piston or you are an expert who enjoys tuning piston weights and airbrakes for maximum performance, the Stalker Scorpion is your best friend.\u003c\/p\u003e\n\u003cp\u003eIf you have any issues or questions about this or other Stalker products, visit our Stalker Owners Group on Facebook here:\u003c\/p\u003e\n\u003cp\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 \u003c\/p\u003e","brand":"STALKER","offers":[{"title":"Default Title","offer_id":52550886261077,"sku":"SP-STAL-43-1.1.1","price":96.0,"currency_code":"CAD","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/1024\/3607\/7909\/files\/image_a9f79c53-1b9b-4edb-82d3-35f054792fe0.jpg?v=1771971320","url":"https:\/\/www.skirmshop.es\/en-ca\/products\/stalker-scorpion-piston-srs-plug-play-edition","provider":"Skirmshop Spain","version":"1.0","type":"link"}
