For us, the label Made in Germany is an indication of origin, proof of quality and much more than just the place of final assembly. As a company with headquarters in Triefenstein and our logistics center in Salt Lake City / Draper, we feel committed to local art of engineering, inventiveness and reliability.

With internal machinery, internal finishing facilities, over 30 active injection molds, and a regional network of suppliers, we clearly differentiate ourselves from our competitors. As one of the few German companies that can almost completely manufature without sourcing parts like rifle stocks (except Magpul PRS), handles or magazines, we are, in addition to our mechanical production, particularly proud of our constantly growing polymer division.

AOT (Articles of Trade) OEM or purchased parts are clearly named by us. Learn more about our production capacities and partners in our NEWS section.
