Airgun Designs Automag was invented in 1985 but the first release to the public was not till 1990 after several revisions.
After its release there have been several more updates starting with Level 6, Level 7, Level 10, RT, RT Pro, XMag, MinImag
The Automag is ruggedly built, the mainbody and A.I.R. valve being manufactured out of stainless steel. The body rail is a black anodized aluminum extrusion and the grip frame manufactured of a carbon composite.
In 1996, Airgun Designs released the Automag RT (RT standing for Reactive Trigger). This revolutionary design required high pressure air (HPA) to operate; the rapid decompression involved in the valve would quickly cause CO2 to liquefy and freeze the valve's components. This valve uses air pressure to quickly reset the trigger after a shot, thus enabling a faster rate of fire. Shootdown became impossible, as these valves recharged faster than anyone could pull the trigger; in fact, due to their design, they heated up under rapid fire and actually experienced shootup instead. Unfortunately, the original design was fed its gas through the marker's rail, and thus was incompatible as an upgrade to older Automags
