{"product_id":"lbe-carbine-length-gas-tube-melonite","title":"LBE Unlimited Carbine-Length Gas Tube – AR-15 Melonite Finish","description":"\u003cp\u003eThe LBE Unlimited Carbine-Length Gas Tube is a direct replacement gas tube designed for AR-15 carbine-length gas systems. This component channels combustion gases from the gas port to the gas key on the bolt carrier group, cycling the action for semi-automatic operation. Whether you're replacing a worn tube or building a new upper receiver, this gas tube restores reliable cycling in standard carbine-length configurations (typically 16-inch barrels with mid-front sight base placement).\u003c\/p\u003e\u003cp\u003eConstructed from steel with a melonite finish, this gas tube resists corrosion and heat-related wear better than uncoated alternatives. Melonite treatment penetrates the steel surface for long-term durability in high round-count environments. Installation requires a gas tube roll pin and is straightforward with basic armorer tools—no professional gunsmithing required, though familiarity with AR-15 assembly is recommended. Compatible with mil-spec upper receivers and low-profile or A2-style gas blocks.\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\u003eLength:\u003c\/strong\u003e Carbine (approximately 9.75 inches)\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 Melonite (black)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInstallation:\u003c\/strong\u003e Drop-in with basic tools (roll pin required, not included)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eIncludes:\u003c\/strong\u003e Gas tube only (roll pin sold separately)\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"LBE Unlimited","offers":[{"title":"Default Title","offer_id":48535423647999,"sku":"LBARGTC-BLK","price":11.95,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0729\/0434\/3807\/files\/5688051.jpg?v=1778982228","url":"https:\/\/doublestackstore.com\/products\/lbe-carbine-length-gas-tube-melonite","provider":"Double Stack Store","version":"1.0","type":"link"}
