Gas tubes are high-wear components subject to carbon fouling and heat stress—replacing a compromised tube restores reliable cycling and prevents gas leaks that cause short-stroking or failure to eject. This is a maintenance part every AR owner should keep on hand.\u003c\/p\u003e\u003cp\u003eManufactured from stainless steel with a nitride finish for corrosion resistance and reduced friction. The nitride treatment extends service life compared to standard stainless tubes. Installation requires gas block removal and a roll pin punch—straightforward for anyone comfortable with basic AR maintenance, though a properly staked gas tube roll pin is essential for reliability.\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 rifle-length gas systems (20\" barrel standard)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaterial:\u003c\/strong\u003e Stainless steel\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFinish:\u003c\/strong\u003e Nitride\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInstallation:\u003c\/strong\u003e Drop-in (requires gas block removal and roll pin installation)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eIncludes:\u003c\/strong\u003e Gas tube\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"San Tan Tactical","offers":[{"title":"Default Title","offer_id":47939799613695,"sku":"STTGTR","price":18.95,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0729\/0434\/3807\/files\/2149963.jpg?v=1766546664","url":"https:\/\/doublestackstore.com\/products\/santan-ar15-gas-tube-ntrd-rfl-lngth","provider":"Double Stack Store","version":"1.0","type":"link"}
