{"product_id":"santan-ar15-gas-tube-ntrd-int-lngth","title":"San Tan Tactical AR-15 Gas Tube – Nitrided, Intermediate Length","description":"\u003cp\u003eThe San Tan Tactical nitrided intermediate-length gas tube is a direct replacement for worn or damaged gas tubes in AR-15 rifles with intermediate-length gas systems. This component channels propellant gases from the barrel's gas port to the bolt carrier group, cycling the action. Upgrading to a nitrided gas tube provides superior corrosion resistance and extended service life compared to standard stainless steel tubes, particularly in high-volume shooting or adverse conditions.\u003c\/p\u003e\u003cp\u003eConstructed from steel with a nitrided finish, this gas tube offers a hard, wear-resistant surface that resists carbon buildup and environmental degradation. Installation is straightforward for anyone familiar with AR-15 assembly—remove the handguard, extract the old tube from the gas block, and install this replacement with a roll pin. No specialized gunsmithing required, though proper roll pin punches are recommended to avoid damaging 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 rifles with intermediate-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 Nitrided\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eGas System Length:\u003c\/strong\u003e Intermediate\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInstallation:\u003c\/strong\u003e Drop-In (requires roll pin installation)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eIncludes:\u003c\/strong\u003e Gas tube only (roll pin not included)\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"San Tan Tactical","offers":[{"title":"Default Title","offer_id":47939784769791,"sku":"STTGTI","price":18.95,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0729\/0434\/3807\/files\/2877964.jpg?v=1766546573","url":"https:\/\/doublestackstore.com\/products\/santan-ar15-gas-tube-ntrd-int-lngth","provider":"Double Stack Store","version":"1.0","type":"link"}
