{"product_id":"cmmg-ar15-barrel-nut","title":"CMMG AR-15 Barrel Nut – Standard Mil-Spec Threading","description":"\u003cp\u003eThe CMMG AR-15 Barrel Nut is a direct replacement component that secures the barrel extension to the upper receiver and provides the mounting platform for your handguard. This is a wear item that should be replaced if threads show damage, if you're switching handguard systems, or during a barrel replacement. CMMG produces this nut to mil-spec dimensions for reliable function with standard AR-15 platform uppers.\u003c\/p\u003e\u003cp\u003eMachined from steel with a phosphate finish for corrosion resistance, this barrel nut features standard wrench flats and requires a barrel nut wrench and torque wrench for proper installation. Installation demands careful torquing to manufacturer specifications and proper alignment of gas tube clearance—professional installation is recommended unless you have armorer-level experience and the correct tools. Not compatible with free-float handguards that use proprietary mounting systems.\u003c\/p\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003ePart Type:\u003c\/strong\u003e Barrel Nut\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCompatible Firearms:\u003c\/strong\u003e AR-15 platform rifles with mil-spec upper receivers\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaterial:\u003c\/strong\u003e Steel\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFinish:\u003c\/strong\u003e Phosphate\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInstallation:\u003c\/strong\u003e Professional Recommended – requires barrel nut wrench, torque wrench, and proper gas tube alignment\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eIncludes:\u003c\/strong\u003e Barrel nut only (no wrench or hardware included)\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"CMMG","offers":[{"title":"Default Title","offer_id":47934699864319,"sku":"CMMG55DA296","price":11.95,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0729\/0434\/3807\/files\/1256892.jpg?v=1766476852","url":"https:\/\/doublestackstore.com\/products\/cmmg-ar15-barrel-nut","provider":"Double Stack Store","version":"1.0","type":"link"}
