Due to Swiss neutrality laws restricting arms exports, SIG licensed production to \u003cstrong\u003eManurhin of France\u003c\/strong\u003e, who manufactured rifles and magazines for military contracts worldwide. These magazines saw service with the \u003cstrong\u003eLebanese Armed Forces\u003c\/strong\u003e, \u003cstrong\u003eFrench Marine Infantry\u003c\/strong\u003e, \u003cstrong\u003ePortuguese military\u003c\/strong\u003e, and \u003cstrong\u003eChilean Armed Forces\u003c\/strong\u003e (via FAMAE). The robust steel construction and reliable feeding system contributed to the platform's reputation for dependability in harsh conditions.\u003c\/span\u003e\u003c\/p\u003e","brand":"SIG","offers":[{"title":"Default Title","offer_id":52668965945666,"sku":"MAG1041","price":49.99,"currency_code":"USD","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0997\/7921\/5682\/files\/IMG_9804__13569.1766178754.1280.1280.jpg?v=1774274655","url":"https:\/\/centerfiresystems.com\/products\/sig-manurhin-model-543-5-56x45mm-30-round-magazine","provider":"Centerfire Systems","version":"1.0","type":"link"}
