Development began after the unsuccessful SG 530-1 design, with SIG opting for a robust \u003cstrong\u003elong-stroke gas piston system with rotating bolt\u003c\/strong\u003e derived from the AK-47 platform. The SG 543 features a shortened \u003cstrong\u003e300mm (11.8\") barrel\u003c\/strong\u003e, compact gas system, folding buttstock, and four-position aperture sights for 100-400 meters. Due to Swiss export restrictions, SIG licensed production to \u003cstrong\u003eManurhin of France\u003c\/strong\u003e. The rifle was adopted by several nations including Lebanon, Portugal, and Chile, where \u003cstrong\u003eFAMAE\u003c\/strong\u003e continues licensed production today. The SG 540 series served as the foundation for the SIG 550, which became the Swiss military's standard service rifle (Stgw 90).\u003c\/span\u003e\u003c\/p\u003e","brand":"Sig Sauer","offers":[{"title":"Default Title","offer_id":52668964995394,"sku":"KIT0401","price":899.99,"currency_code":"USD","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0997\/7921\/5682\/files\/IMG_9811__60310.1766513598.1280.1280.jpg?v=1774274654","url":"https:\/\/centerfiresystems.com\/products\/sig-543-folding-stock-carbine-parts-kit-5-56x45mm-with-intact-barrel-matching-serials-lebanese-contract","provider":"Centerfire Systems","version":"1.0","type":"link"}
