{"product_id":"cmmg-gas-tube-kit-rifle-w-pin","title":"CMMG Gas Tube Kit Rifle Length with Roll Pin","description":"\u003cp\u003eThis CMMG rifle-length gas tube kit provides a direct replacement for worn, damaged, or corroded gas tubes in AR-15 platforms. The gas tube directs propellant gases from the barrel's gas port back to the bolt carrier group, cycling the action. Over time, gas tubes can erode from heat and corrosive residue, leading to cycling issues. This kit ensures reliable gas operation and is essential for builds or repairs involving rifle-length gas systems (typically 15+ inch barrels).\u003c\/p\u003e\u003cp\u003eManufactured from stainless steel with a corrosion-resistant finish, this gas tube is built to withstand the high temperatures and pressures of repeated firing. Installation requires removal of the handguard and gas block, plus driving out the old roll pin and installing the new one included in this kit. While mechanically straightforward, proper alignment and roll pin installation requires patience and the right tools—armorers' tools and a roll pin punch set are recommended.\u003c\/p\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003ePart Type:\u003c\/strong\u003e Gas Tube Kit (Rifle Length)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCompatible Firearms:\u003c\/strong\u003e AR-15 platforms with rifle-length gas systems\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 Requires armorer-level tools and knowledge; roll pin installation recommended with proper punches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eIncludes:\u003c\/strong\u003e Rifle-length gas tube, roll pin\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"CMMG","offers":[{"title":"Default Title","offer_id":47934699307263,"sku":"CMMG55DA196","price":19.95,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0729\/0434\/3807\/files\/1256859.jpg?v=1766476808","url":"https:\/\/doublestackstore.com\/products\/cmmg-gas-tube-kit-rifle-w-pin","provider":"Double Stack Store","version":"1.0","type":"link"}
