{"product_id":"cmc-ar15-gas-tube-mid-length","title":"CMC Triggers AR-15 Gas Tube – Mid-Length","description":"\u003cp\u003eThe CMC Triggers AR-15 Gas Tube channels propellant gases from the barrel's gas port to the bolt carrier group, cycling the action. This mid-length tube is a direct replacement for worn, damaged, or fouled factory tubes, restoring reliable function in AR-15 platforms with mid-length gas systems. Mid-length systems are common on 14.5\" to 18\" barrels and offer smoother recoil impulse compared to carbine-length systems.\u003c\/p\u003e\u003cp\u003eConstructed from stainless steel with a corrosion-resistant finish for durability under repeated high-temperature gas exposure. Installation requires disassembly of the handguard and removal of the gas block—basic armorer-level work with standard tools. The tube includes a roll pin for gas block attachment.\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 rifles with mid-length gas systems (typically 14.5\"–18\" barrels)\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 coating\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInstallation:\u003c\/strong\u003e Armorer-level (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":47943488143615,"sku":"CMC81623","price":18.95,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0729\/0434\/3807\/files\/1254122.jpg?v=1766578350","url":"https:\/\/doublestackstore.com\/products\/cmc-ar15-gas-tube-mid-length","provider":"Double Stack Store","version":"1.0","type":"link"}
