The SIG MPX ships from the factory with a tapered barrel shoulder that prevents the proper seating of most aftermarket muzzle devices. This collar solves that issue by converting the factory profile to a true \u003cstrong\u003e90-degree shoulder\u003c\/strong\u003e, providing the correct mounting interface for standard thread-on compensators, brakes, and blast diverters.\u003c\/span\u003e\u003c\/p\u003e\n\n\u003cp\u003e\u003cspan style=\"font-size: 14pt;\"\u003eMachined from rugged \u003cstrong\u003e4140 steel\u003c\/strong\u003e and finished with a corrosion-resistant \u003cstrong\u003ephosphate\u003c\/strong\u003e coating, this collar is built to withstand the heat and pressure of regular \u003cstrong\u003e9mm\u003c\/strong\u003e fire while maintaining concentric alignment. As a \u003cstrong\u003eMade in USA\u003c\/strong\u003e Midwest Industries component, it is engineered to the same standards as the company's well-known handguard and optic-mount lines for the SIG MPX platform.\u003c\/span\u003e\u003c\/p\u003e\n\n\u003cp\u003e\u003cspan style=\"font-size: 14pt;\"\u003eInstallation is straightforward: the collar threads onto the SIG MPX \u003cstrong\u003e9mm\u003c\/strong\u003e barrel shoulder, and your chosen muzzle device then threads onto the collar, indexing against the new \u003cstrong\u003e90-degree shoulder\u003c\/strong\u003e for a solid, repeatable fit. Whether you are upgrading a factory MPX carbine or building a custom \u003cstrong\u003e9mm\u003c\/strong\u003e SBR or pistol, this adapter delivers the proper shoulder geometry needed to securely mount your preferred muzzle hardware.\u003c\/span\u003e\u003c\/p\u003e","brand":"Midwest Industries","offers":[{"title":"Default Title","offer_id":55333135057218,"sku":"MIMPX9MMS","price":11.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0997\/7921\/5682\/files\/alt_579d7a79-3722-48e1-9b38-2f0bd90e99d1.jpg?v=1785166588","url":"https:\/\/centerfiresystems.com\/products\/midwest-industries-muzzle-device-collar-sig-mpx-9mm-phosphate","provider":"Centerfire Systems","version":"1.0","type":"link"}
