Gas tubes are wear items that can corrode, bend, or develop carbon buildup over time—this nitrided model offers improved corrosion resistance and durability compared to standard stainless steel tubes, making it a solid choice for shooters who maintain their rifles regularly or operate in harsh environments.\u003c\/p\u003e\u003cp\u003eConstructed from quality steel with a salt bath nitride finish, this tube provides superior surface hardness and corrosion protection. Installation requires removal of the handguard and gas block, which most competent shooters can handle with basic tools, though a roll pin punch set and some care are necessary to avoid damaging the gas block. The tube includes a roll pin for securing to the gas block.\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\u003eCompatible Firearms:\u003c\/strong\u003e AR-15 platforms with mid-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 Salt Bath Nitride (Nitrided)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eGas System Length:\u003c\/strong\u003e Mid-Length\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInstallation:\u003c\/strong\u003e Moderate DIY (requires handguard and gas block removal)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eIncludes:\u003c\/strong\u003e Roll pin\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"San Tan Tactical","offers":[{"title":"Default Title","offer_id":47939788341503,"sku":"STTGTM","price":18.95,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0729\/0434\/3807\/files\/2149962.jpg?v=1766546592","url":"https:\/\/doublestackstore.com\/products\/santan-ar15-gas-tube-ntrd-mid-lngth","provider":"Double Stack Store","version":"1.0","type":"link"}
