This manual presents the necessary engineering data, manufacturing procedures, and machinist drawings for the conversion of the KG–99 family of semi–automatic pistols.

Into ultra–compact, fully automatic sub-machine guns, which fire from an open bolt.

The information provided in this manual applies to conversion of the Interdynamic KG–9, KG99 MINI, INTRATEC TEC–9, and TEC–9 MINI.

The forerunner of this series of weapons is the KG–9, a semi–automatic pistol, which fires from the open bolt. Because of the limited number of KG–9’s produced, full auto conversion of these will not be addressed in this manual.
