{"product_id":"wmd-gas-tube-mid-length-nitromet","title":"WMD Guns NitroMet Gas Tube – Mid-Length AR-15","description":"\u003cp\u003eThe WMD Guns NitroMet Gas Tube is a direct replacement for mid-length AR-15 gas systems. Built for shooters who demand long-term reliability under high round counts and harsh conditions, this gas tube features WMD's proprietary NitroMet coating—a surface treatment that significantly reduces carbon fouling and resists corrosion better than standard stainless steel tubes. Mid-length systems are favored for their balanced gas pressure and reduced recoil impulse compared to carbine-length setups, making this an ideal component for builds prioritizing accuracy and smoother cycling.\u003c\/p\u003e\u003cp\u003eThe tube is constructed from 304 stainless steel and treated with WMD's NitroMet process, which penetrates the metal surface to create a self-lubricating, ultra-hard finish. This coating prevents gas tube erosion and makes carbon buildup wipe away with minimal effort. Installation is straightforward for anyone familiar with AR-15 assembly—this is a drop-in part requiring only a roll pin and gas block alignment. Includes roll pin.\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 Systems\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaterial:\u003c\/strong\u003e 304 Stainless Steel\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFinish:\u003c\/strong\u003e NitroMet Coating\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInstallation:\u003c\/strong\u003e Drop-In\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eIncludes:\u003c\/strong\u003e Roll Pin\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"WMD Guns","offers":[{"title":"Default Title","offer_id":47939839590655,"sku":"WMDNMGTML","price":15.95,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0729\/0434\/3807\/files\/5584908.jpg?v=1766548542","url":"https:\/\/doublestackstore.com\/products\/wmd-gas-tube-mid-length-nitromet","provider":"Double Stack Store","version":"1.0","type":"link"}
