The Atari XG-1 light gun is a video game controller which was released in 1987. Atari's only light gun, it is compatible with the Atari 8-bit computers, Atari 7800, and Atari 2600. It was bundled with the Atari XEGS Deluxe home computer and video game console combination system, and with the light gun game Bug Hunt for the 7800 as model XES2001 for US$34.95. Atari eventually released five light gun games on the 7800 and one on the 2600 (Sentinel).

A light gun is a pointing device for computers and a control device for arcade and video games, typically shaped to resemble a pistol.
