Ferengi phaser

The Ferengi phaser was a type of phaser classified as a plasma weapon used by the Ferengi which fired a forced plasma beam. 

In 2369, the Rakhari criminal Croden used a Ferengi phaser when he went into holosuite one to steal a valuable egg item from the two Miradorns Ah-Kel and Ro-Kel. Constable Odo later mentioned that it was curious he used such a weapon and suggested Quark behind this. 

In the same year, the group of renegade Borg, led by Lore, utilized similar weapons as implants. 

In 2374, Quark and some of his gang took Ferengi firearms with them to trade Keevan for Ishka in a prisoner exchange on the space station Empok Nor. Later in 2375, he took it with him to AR-558 to defend himself and his nephew Nog from Jem'Hadar.
