Designed specifically for the higher pressures and larger case head of the .450 Bushmaster, this bolt assembly ensures proper headspacing and reliable extraction in hunting and defensive applications where this cartridge excels at close to medium range.\u003c\/p\u003e\u003cp\u003eManufactured with a NiB-X nickel boron coating, this bolt assembly offers enhanced lubricity and corrosion resistance compared to standard phosphate finishes. The coating reduces friction during cycling and simplifies cleaning after extended use. Installation is straightforward for anyone familiar with AR-15 bolt carrier group maintenance—extract the firing pin retaining pin, remove the cam pin, and the bolt slides out of the carrier. Professional installation is recommended if you're unfamiliar with AR-15 disassembly or need to verify headspacing with your specific barrel.\u003c\/p\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003ePart Type:\u003c\/strong\u003e Bolt Assembly\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCompatible Firearms:\u003c\/strong\u003e AR-15 chambered in .450 Bushmaster\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 NiB-X Nickel Boron\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInstallation:\u003c\/strong\u003e Drop-In (headspacing verification recommended)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eIncludes:\u003c\/strong\u003e Bolt, extractor, ejector, gas rings, cam pin, firing pin, firing pin retaining pin\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"WMD Guns","offers":[{"title":"Default Title","offer_id":47939837919487,"sku":"WMDNIBXBA450","price":81.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0729\/0434\/3807\/files\/5584899.jpg?v=1766548122","url":"https:\/\/doublestackstore.com\/products\/wmd-bolt-assembly-450-bushmaster","provider":"Double Stack Store","version":"1.0","type":"link"}
