In 1978 they licensed production of the 540, 542, and 543 to Manurhin in France, to sidestep Swiss export laws. The rifles were sold to a wide variety of small nations in Africa, South America, Asia, and the Middle East &mdash; including Lebanon, where this example came from. A batch of 542 and 543 kits came into the US from Lebanon recently, and Troy Ess at TTE Precision Metalwerks developed semiauto receivers for them.<br \/>\n<!--more--><\/p>\n<p>Disclaimer: I paid in full for everything in this video.<\/p>\n<p>The best firearms reference books: <a href=\"https:\/\/www.headstamppublishing.com\" target=\"_blank\">https:\/\/www.headstamppublishing.com<\/a><\/p>\n<p><a href=\"https:\/\/www.youtube.com\/redirect?event=video_description&#038;redir_token=QUFFLUhqa3U2bEltVWh4OGlZRUlpalhNWkdGVlJqRjFPd3xBQ3Jtc0ttVTd1YmZWeG5CXzZZQ3p4SWhfdFpBb2dNSTJTTXhsd3VmSDFyWHY4N010Tk93TGdhSm9LNDRrdXRsaHlfZ1A4REJ1RGMyU2dpN29pTXY5dTdZaFBtbFd5R1JQMThvNFNMcU5Ea203YWRiTHQtSjdyNA&#038;q=http%3A%2F%2Fwww.floatplane.com%2Fchannel%2FForgottenWeapons&#038;v=s9W14CwIT6Y\" target=\"_blank\">http:\/\/www.floatplane.com\/channel\/For&#8230;<\/a><\/p>\n<p>Cool Forgotten Weapons merch! <a href=\"http:\/\/shop.forgottenweapons.com\" target=\"_blank\">http:\/\/shop.forgottenweapons.com<\/a><\/p><\/blockquote>\n","protected":false},"excerpt":{"rendered":"<p>Forgotten Weapons Published 23 May 2026 SIG introduced the 540 series of rifles in 1973, which included the full-length 540 in 5.56mm, the 541 in a number of experimental calibers for the Swiss military, the 542 in 7.62mm NATO, and the 543 carbine with an 11.8&#8243; (300mm) barrel in 5.56mm.
