{"product_id":"cmc-ar15-gas-tube-rifle-length","title":"CMC Triggers AR-15 Gas Tube – Rifle Length","description":"\u003cp\u003eThis CMC Triggers gas tube is a direct replacement for worn, damaged, or corroded rifle-length gas tubes in AR-15 platform rifles. Gas tubes channel propellant gases from the gas port in the barrel back to the bolt carrier group, cycling the action. Over time, gas tubes can develop carbon buildup, corrosion, or physical damage from improper installation or removal. Replacing a compromised gas tube restores reliable cycling and prevents short-stroking or failure to eject malfunctions.\u003c\/p\u003e\u003cp\u003eConstructed from stainless steel with a corrosion-resistant finish, this tube is designed for rifle-length gas systems (typically found on 20-inch barrels). Installation requires removal of the handguard and gas block, alignment of the gas tube with the gas port and upper receiver gas key, and proper roll pin staking. A roll pin punch set and armorer's wrench are recommended. This is a straightforward upgrade for anyone comfortable with AR-15 disassembly, though first-time builders may prefer professional installation to ensure correct alignment.\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 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 Intermediate – Requires Gas Block Removal\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eIncludes:\u003c\/strong\u003e Gas Tube, Roll Pin\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"CMC Triggers","offers":[{"title":"Default Title","offer_id":47943488962815,"sku":"CMC81625","price":18.95,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0729\/0434\/3807\/files\/1254127.jpg?v=1766578389","url":"https:\/\/doublestackstore.com\/products\/cmc-ar15-gas-tube-rifle-length","provider":"Double Stack Store","version":"1.0","type":"link"}
