Dillon Aero, Inc. designs, develops, manufactures, and supports the Dillon Aero M134 Gatling Gun, as well as a wide range of supporting and related products.  Initially, Dillon produced components to modernize the General Electric GAU-2 Minigun.  The GAU-2 Minigun, also known as the M134, had been in service since the 1960’s and was suffering from a combination of innate design flaws, poor spares supply, and no product support.  By the time Dillon Aero began work on the project, the Minigun was on the verge of retirement.
