{"product_id":"wmd-gas-tube-rifle-length-nitromet","title":"WMD Guns Gas Tube Rifle Length NiTroMet","description":"\u003cp\u003eThe WMD Guns NiTroMet gas tube is a direct replacement for rifle-length AR-15 gas systems. Gas tubes are critical wear components that can erode over time from hot, corrosive gases—this nitride-treated option provides enhanced corrosion resistance and durability compared to standard stainless steel tubes. If you're rebuilding an upper receiver or replacing a worn gas tube, this is a straightforward upgrade.\u003c\/p\u003e\u003cp\u003eThe NiTroMet surface treatment bonds a hard nitride layer to the steel, extending service life and reducing friction. This is a drop-in part requiring only a gas block roll pin for installation. Standard rifle-length dimensions ensure compatibility with any mil-spec AR-15 upper receiver using a rifle-length gas system (typically found on 20-inch barrels).\u003c\/p\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003ePart Type:\u003c\/strong\u003e Gas Tube\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eLength:\u003c\/strong\u003e Rifle (standard for 20\" barrel gas systems)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCompatible Firearms:\u003c\/strong\u003e AR-15 \/ M16 platforms with rifle-length gas systems\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaterial:\u003c\/strong\u003e Steel\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFinish:\u003c\/strong\u003e NiTroMet Nitride\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInstallation:\u003c\/strong\u003e Drop-In (requires gas block roll pin)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eIncludes:\u003c\/strong\u003e Gas tube\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"WMD Guns","offers":[{"title":"Default Title","offer_id":47939848863999,"sku":"WMDNMGTR","price":18.95,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0729\/0434\/3807\/files\/5594884.jpg?v=1766548613","url":"https:\/\/doublestackstore.com\/products\/wmd-gas-tube-rifle-length-nitromet","provider":"Double Stack Store","version":"1.0","type":"link"}
