Cardassian phase-disruptor rifle
The Cardassian phase-disruptor rifle or Cardassian disruptor rifle or Cardassian disruptor or Cardassian rifle was a type of disruptor rifle, designed and used by the Cardassians.

Specifications 
The weapon had a 4.7 megajoules power capacity, with a 3 millisecond recharge and 2 beam settings. It was comparable to the Starfleet type 3 phaser, but was more powerful with fewer options. () 

They could also be fitting with an optional shoulder strap. ()

History 
During the Cardassian Occupation of Bajor, the Bajorans captured a lot of these rifles, allowing resistance fighters, such as Kira Nerys become intimately familiar with their function. Major Kira's opinion of it was "[t]his is a good weapon… solid and simple. You can drag it through the mud and it'll still fire." 

When Kira later trained Tora Ziyal the basics on how to use both weapons in 2373, Kira recommended "I think you should stick with the Cardassian rifle. It's smaller, easier to use, and if we get boarded I don't want you to have to think too much about the weapon your using" ()

In an alternate 2404, the Klingon Korath modified a Cardassian disruptor of this type to emit a nadion pulse. He was working on the modification with a laser tool upon the arrival of Admiral Kathryn Janeway to his laboratory, where he showed his handiwork off to her upon its completion. Janeway described the modification to be "[i]mpressive, but that's not what I've come for," which Korath agreed, replying, "No. You've come for something far more dangerous." ()

Background information 

According to the Star Trek: The Visual Dictionary (p. 73), the components and functions of the phase-disruptor rifle were noted. It described the top of pistol grip as the location of the "beam intensity and width adjustment", the "isotolinium power cell" located behind the "main targeting system", and the "emitter crystal" located at the tip of the barrel. It further describes the smaller hand-held version, which makes up the rifles rear hand grip, as a "phase-disruptor pistol".

Several Cardassian disruptor rifles were sold as part of various Star Trek auctions, which described its dimensions as approx. 21 ¾ x 8 x 3 ½ inches.
