In the world of Airsoft, there is a common abbreviation known to all players: AEG. The three letters stand for "automatic electric gun." It is a category of Airsoft weapon in which BBs are projected by an internal electric motor. Considered the cream of the crop by Airsoft enthusiasts, the most powerful weapons in the game are usually AEGs.

Originally developed in Japan, Airsoft AEG guns have rapidly become the standard in Airsoft competition across the world. At its most basic, the motor in an AEG gun drives a number of gears, which compress a piston assembly up against a spring. When the piston is released, the compressed spring launches the ammunition through the barrel. The motor then repeats the process as long as the trigger is pressed.

As opposed to spring guns, in which the weapon must be manually cocked before every shot, the electric motor on an AEG does the cocking automatically. This is what gives these types of guns their semi-auto and full-auto functions. Such motors can have varying levels of power depending on the model. Nevertheless, most automatic electric weapons capable of shooting at 300 feet per second or higher are considered AEGs.

A cool-looking and powerful Airsoft AEG gun is the Marui Steyr AUG. This user-friendly gun has excellent range, offers a strong grip and comes with a convenient mount already attached. This mount allows owners to install any scope they need without additional accessories. Tokyo Marui's reputation in the field of custom Airsoft AEG guns is unparalleled and the Marui Steyr AUG is no exception to this rule.
