The SIG 556 semi-automatic rifle was announced in 2006 as a rifle for civilian and law-enforcement use. It was produced by international SIGARMS (now SIG Sauer arms corporation) and intended primarily for the US market. The SIG 556 is based on the SIG SG 550 assault rifle, still in use by the Swiss army today. In the Swiss Army, it is designated as ‘Stgw 90’ or ‘Sturmgewehr 90’ (‘SG’ also refers to the word ‘Sturmgewehr’). It’s limited to semi-automatic fire only, thus being legal in most countries that permit civilians to own rifles. SIG Sauer also produces a SIG 556 SWAT semi-automatic rifle which has a different butt stock and a 4-rail forend.
