Hämmerli is a formerly Swiss, now German manufacturer of air guns and firearms aimed mostly at target shooting, especially Olympic events governed by the International Shooting Sport Federation. In 2006, Hämmerli was acquired by Umarex; production and customer support moved to Ulm, Germany. The Hämmerli brand dates back to 1863 when Johann Ulrich Hämmerli founded the company to make rifle barrels for the Swiss Army. Since then Hämmerli has manufactured rifle barrels, firearms, and firearm components. In 1950, Hämmerli produced Olympic rifles that were used to win gold medals at the next four Olympics.
