{"product_id":"cmmg-detent-rcver-pivot-td-spring","title":"CMMG Receiver Detent, Pivot Pin \u0026 Takedown Pin Spring","description":"\u003cp\u003eThe CMMG receiver detent and spring set is a small but essential part of the AR-15 lower receiver assembly. This detent and spring work together to secure the pivot pin and takedown pin in place, providing the tension that keeps pins from walking out during operation. These parts commonly wear out or get lost during disassembly and maintenance, making replacements a necessary item for any serious AR builder or armorer.\u003c\/p\u003e\u003cp\u003eManufactured from hardened steel with a corrosion-resistant finish, these CMMG detents and springs are built to MILSPEC dimensions for reliable fit and function. Installation is straightforward for anyone familiar with AR lower receiver assembly, though a detent installation tool or slave pin can make the process easier and prevent launching small parts across your workspace. These are drop-in replacement parts that require no modification or fitting.\u003c\/p\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003ePart Type:\u003c\/strong\u003e Receiver Detent \u0026amp; Spring Set\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCompatible Firearms:\u003c\/strong\u003e AR-15 Platform\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaterial:\u003c\/strong\u003e Hardened Steel (Detent), Spring Steel (Spring)\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 Armorer Skills Required)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eIncludes:\u003c\/strong\u003e Detent \u0026amp; Spring\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"CMMG","offers":[{"title":"Default Title","offer_id":47934697242879,"sku":"CMMG55CA581","price":1.95,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0729\/0434\/3807\/files\/4872527.jpg?v=1766476550","url":"https:\/\/doublestackstore.com\/products\/cmmg-detent-rcver-pivot-td-spring","provider":"Double Stack Store","version":"1.0","type":"link"}
