{"product_id":"luth-ar-pistol-gas-tube","title":"Luth-AR Pistol Gas Tube – AR-15 Pistol-Length Systems","description":"\u003cp\u003eThe Luth-AR Pistol Gas Tube is a direct replacement for worn or damaged gas tubes in AR-15 pistol-length gas systems. Essential for cycling reliability, the gas tube channels propellant gases from the barrel to the bolt carrier group, making it critical to function. Whether you're building a compact AR pistol or maintaining an existing upper, this tube ensures proper gas system operation for consistent cycling.\u003c\/p\u003e\u003cp\u003eManufactured from stainless steel with a corrosion-resistant finish, this tube measures the standard pistol length (approximately 6.75 inches from the gas block journal to the upper receiver). Installation requires a roll pin punch and basic tools—straightforward for builders familiar with AR assembly, though a qualified gunsmith is recommended for first-time installations to ensure proper alignment and gas port timing.\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 Pistol-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 Drop-In (basic tools and roll pin required; gunsmith recommended for first-time builders)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eIncludes:\u003c\/strong\u003e Gas Tube, Roll Pin\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"Luth-AR","offers":[{"title":"Default Title","offer_id":47938426994943,"sku":"LUTHBL-04B","price":11.95,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0729\/0434\/3807\/files\/1290062.jpg?v=1766514480","url":"https:\/\/doublestackstore.com\/products\/luth-ar-pistol-gas-tube","provider":"Double Stack Store","version":"1.0","type":"link"}
