{"product_id":"cmc-ar15-gas-tube-carbine-length","title":"CMC Triggers AR-15 Gas Tube – Carbine Length","description":"\u003cp\u003eThe CMC Triggers AR-15 Gas Tube in carbine length delivers reliable gas system operation for standard carbine-length AR-15 builds and replacements. This gas tube channels propellant gases from the barrel's gas port to the gas key on the bolt carrier group, cycling the action for semi-automatic fire. Replace worn or damaged tubes, or use when building a custom upper receiver with a carbine-length gas system (typically paired with barrels 10–18 inches).\u003c\/p\u003e\u003cp\u003eManufactured from stainless steel with a Melonite finish for corrosion resistance and heat tolerance. Installation requires disassembly of the upper receiver and removal of the handguard—a roll pin punch and basic armorer's tools are necessary to remove the old gas tube roll pin and install the new tube. This is a standard drop-in component for builders and armorers familiar with AR-15 assembly.\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 carbine-length gas systems\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eGas System Length:\u003c\/strong\u003e Carbine\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 Melonite\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInstallation:\u003c\/strong\u003e Drop-in with basic armorer tools (roll pin punch required)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eIncludes:\u003c\/strong\u003e Gas tube and roll pin\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"CMC Triggers","offers":[{"title":"Default Title","offer_id":47943488012543,"sku":"CMC81622","price":17.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0729\/0434\/3807\/files\/1254118.jpg?v=1766578321","url":"https:\/\/doublestackstore.com\/products\/cmc-ar15-gas-tube-carbine-length","provider":"Double Stack Store","version":"1.0","type":"link"}
