KG9 9MM Machine Gun






Gun is in excellent condition. It has the more desirable fore grip installed on the shroud.  You don’t see very many of these around!

The KG-9 is an American version of the Swedish Interdynamic MP-9.

The KG-9 was designed as a cheap submachine gun for military applications however Interdynamic was unable to drum up any interest among governments, and the subgun never entered production in Sweden. Unwilling to give up on the design, Interdynamic set up a U.S. subsidiary intended principally to market a version, named the KG-9 after the two principal partners Kelgren & Garcia, to civilians under the name Interdynamic USA. In 1982, after less than a year of production, the ATF classified the KG-9 as a Title II “machine gun” on the basis that its open-bolt design made it “readily convertible” to fully-automatic fire. This forced Interdynamic to redesign the KG-9 into a closed bolt system, birthing the KG-99. In 1984 Kelgren sold his shares to Garcia, who renamed the company to Intratec. They rebranded the KG-99 as the Tec-9 and changed a few features.
