Gas tubes are critical to cycling reliability—over time, they can erode from heat and fouling, leading to function issues. This OEM-grade replacement restores proper gas flow to the bolt carrier group, ensuring consistent cycling with factory or aftermarket parts.\u003c\/p\u003e\u003cp\u003eConstructed from stainless steel with a durable finish to resist corrosion and heat stress. Installation requires removal of the handguard and gas block, with a roll pin securing the tube to the gas block. This is a straightforward task for shooters comfortable with AR maintenance, though a roll pin punch set and bench vise or armorer's block are recommended. Includes roll pin.\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, M4 (Carbine-Length Gas System)\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 Corrosion-Resistant\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInstallation:\u003c\/strong\u003e Drop-In with Basic Tools\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eIncludes:\u003c\/strong\u003e Roll Pin\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"Armaspec","offers":[{"title":"Default Title","offer_id":47934613553407,"sku":"ARMASPEC653-CL","price":13.95,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0729\/0434\/3807\/files\/2945790.jpg?v=1766473225","url":"https:\/\/doublestackstore.com\/products\/armaspec-gas-tube-carbine-length","provider":"Double Stack Store","version":"1.0","type":"link"}
