{"product_id":"cmmg-gas-tube-kit-carbine-w-pin","title":"CMMG Gas Tube Kit Carbine with Roll Pin – AR-15 Mid-Length","description":"\u003cp\u003eThe CMMG Gas Tube Kit provides a factory-spec replacement gas tube for carbine-length AR-15 gas systems. This kit is essential when building a new upper receiver or replacing a worn, damaged, or corroded gas tube that's causing cycling issues. The gas tube channels high-pressure combustion gases from the barrel's gas port back to the bolt carrier group, ensuring reliable semi-automatic operation.\u003c\/p\u003e\u003cp\u003eManufactured from 304 stainless steel with a corrosion-resistant finish, this tube is built to withstand sustained heat and gas exposure. The kit includes a stainless steel roll pin for securing the tube to the gas block. Installation requires basic gunsmithing tools: a roll pin punch set, hammer, and gas block alignment. While mechanically inclined shooters can complete this as a drop-in replacement, proper alignment is critical for function and safety.\u003c\/p\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003ePart Type:\u003c\/strong\u003e Gas Tube Kit\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCompatible Firearms:\u003c\/strong\u003e AR-15 carbine-length gas systems\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaterial:\u003c\/strong\u003e 304 stainless steel\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFinish:\u003c\/strong\u003e Stainless steel\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInstallation:\u003c\/strong\u003e Basic gunsmithing skills required\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eIncludes:\u003c\/strong\u003e Gas tube, stainless steel roll pin\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"CMMG","offers":[{"title":"Default Title","offer_id":47934699208959,"sku":"CMMG55DA193","price":16.95,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0729\/0434\/3807\/files\/1256855.jpg?v=1766476798","url":"https:\/\/doublestackstore.com\/products\/cmmg-gas-tube-kit-carbine-w-pin","provider":"Double Stack Store","version":"1.0","type":"link"}
