Instead of fumbling with the factory two-position gas valve, the DISCARDER allows shooters to dial in gas flow for suppressed or unsuppressed fire, reducing recoil impulse, minimizing gas blowback, and extending component life. This system is particularly valuable for SCAR owners who run suppressors frequently or shoot with varying ammunition weights.\u003c\/p\u003e\u003cp\u003eMachined from hardened steel with a nitrided finish, the DISCARDER integrates a numbered adjustment dial directly into the carrier assembly. Gas adjustment is performed by rotating the dial—no screws, no tools, no disassembly required. Installation requires removal of the factory gas piston and carrier; while straightforward for experienced owners, those unfamiliar with SCAR disassembly may prefer professional installation. The system maintains full reliability across settings when properly tuned to your ammunition and suppressor combination.\u003c\/p\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003ePart Type:\u003c\/strong\u003e Adjustable Gas Piston System\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCompatible Firearms:\u003c\/strong\u003e FN SCAR 16S, FN SCAR 17S\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaterial:\u003c\/strong\u003e Hardened Steel\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFinish:\u003c\/strong\u003e Nitrided\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInstallation:\u003c\/strong\u003e Moderate – Requires Disassembly of Gas System (Professional Recommended for Inexperienced Users)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eIncludes:\u003c\/strong\u003e DISCARDER Assembly, Installation Instructions\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"KNS Precision, Inc.","offers":[{"title":"Default Title","offer_id":47943822180607,"sku":"KNSDISCARDER","price":155.95,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0729\/0434\/3807\/files\/4872697.jpg?v=1766602211","url":"https:\/\/doublestackstore.com\/products\/kns-discarder-gas-adjust-for-scar","provider":"Double Stack Store","version":"1.0","type":"link"}
