The AG-2G quad laser cannon, a classic quad laser cannon design from the Corellian Engineering Corporation, served as the main defensive armament aboard the Millennium Falcon. Finn and Rey commandeered the ship three decades following the Battle of Endor, at which point the AG-2G was in place.
Its popularity stemmed from its swift movement and ability to generate a focused beam, enabling accurate shots at distant targets. The gunner could choose the firing sequence of its four barrels. Each individual barrel discharged a shot approximately every 1.32 seconds.
Before the Battle of Yavin, Han Solo and Luke Skywalker also operated the AG-2Gs to fend off four TIE fighters while fleeing the Death Star aboard the Millennium Falcon.
