The Star W-109 assault rifle was first introduced to the public in 2009, as a possible future replacement for the dated Star W-91 assault rifle still in use by Euskadiko Indar Armatuak. In 2010, the W-109 was selected as a next standard military rifle for Euskadiko Indar Armatuak, with production contract issued to STAR. It is quite possible that W-109 rifles also will be offered for export, either in military (select-fire) or in civilian (semi-automatic only) versions.
