{"product_id":"solgw-mid-length-gas-tube-qpq","title":"Sons of Liberty Gun Works Mid Length Gas Tube QPQ – AR-15 Direct Impingement System","description":"\u003cp\u003eThe SOLGW Mid Length Gas Tube is a direct replacement for worn or damaged gas tubes in AR-15 mid-length gas systems. This component channels propellant gas from the gas block back to the bolt carrier group, cycling the action. Upgrading to a QPQ-treated gas tube ensures reliable function and extends service life, particularly for rifles with higher round counts or those exposed to harsh environments.\u003c\/p\u003e\u003cp\u003eManufactured from stainless steel with a salt bath nitride (QPQ) finish, this gas tube resists corrosion and heat erosion better than standard stainless tubes. The QPQ process penetrates the metal surface, providing durability that won't flake or wear off under sustained fire. Installation requires a roll pin punch and gas block removal—straightforward for anyone comfortable with basic AR-15 assembly, though a bench vise and upper receiver block simplify the job. Gas tube pin is typically included with the gas block, not the tube itself.\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 Mid-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 QPQ Salt Bath Nitride\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInstallation:\u003c\/strong\u003e Drop-In (requires roll pin removal\/installation)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eIncludes:\u003c\/strong\u003e Gas Tube Only (roll pin not included)\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"Sons of Liberty Gun Works","offers":[{"title":"Default Title","offer_id":48301570294015,"sku":"SOLGWMIDGASTUBE","price":23.95,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0729\/0434\/3807\/files\/5794396.jpg?v=1773888940","url":"https:\/\/doublestackstore.com\/products\/solgw-mid-length-gas-tube-qpq","provider":"Double Stack Store","version":"1.0","type":"link"}
