Umarex Sportwaffen GmbH & Co. KG is a manufacturer of air guns (including Umarex air pistols such as the Beretta Elite II), tear-gas and signal pistols, paintball markers under the RAM brand and airsoft guns, based in Arnsberg, Germany. The firm was founded in 1972.
In 1993 the Walther Arms firm was acquired by Umarex, who continued to manufacture under the Walther name in Ulm and Arnsberg. In 2010, Röhm Gesellschaft, the firearms division of Röhm GmbH was also acquired.
The US subsidiary of Umarex is called Umarex USA and was created in 2006 after acquiring the US marketers of the RWS brand (formerly part of Dynamit Nobel), which they continue to market. Umarex USA markets Umarex airguns in addition to many other airguns under license from various firearm brands. Umarex USA entered the tactical rimfire market in 2009 with the importation of Walther-made Colt M4 and M16 .22 LR guns. In late 2010, the company began offering a Turkish-made M1911A1 chambered in .45 ACP. Umarex USA also markets entry-level airsoft guns under the brands Combat Zone and Elite Force, and a North American exclusive brand, Tactical Force.
