The Steyr Aug is a “bull-pup” assault rifle manufactured by Steyr Mannlicher GmbH & Co KG. It is in use by dozens of police and military units around the world. Members of the Indonesian security forces are regularly pictured carrying Steyr AUG assault rifles, and the weapon is known to be used by BRIMOB, KOPASKA, KOPASSUS and Detachment 88. An Australian variant. the F88, is manufactured under license by Thales Australia at its Lithgow factory. It is possible that the Australian version is also in use in West Papua.
Members of BRIMOB have regularly been photographed carrying Steyr AUG weapons in Papua, including when policing protests, and when on patrol.
The sight is manufactured by Swarovski Optik.
