The Bajoran phaser rifle was a type of directed energy weapon, a hand-held phaser weapon modified into a rifle stock configuration of use in combat by the military forces of the Bajoran Provisional Government, both in the Bajoran Resistance and the subsequent Bajoran Militia.
Based on the standard Bajoran phaser pistol, this phaser rifle adaptation used the same phaser pistol technology used in the smaller weapon has similar adaptations as other Bajoran weapons, foregoing a prefire chamber and instead using six pinpoint energy beams that precede the weapon blast as a prefire matrix, focusing the discharge after it leaves the weapon. This is the main dissimilarity between Bajoran weapons and their Federation Starfleet counterparts that utilize a built-in prefire chamber.
Bajoran phaser weapons use a rechargeable isotolinium ampule as a power battery, although some units of this type have been retrofit with sarium krellide energy cells in order to be used with Starfleet chargers. Early models of the rifle unit, besides being ruggedized, also utilize a sensor that acts as a seeker/tracker, using infrared radiation and biogenic profiling to discriminate fire against Cardassian lifesigns, in order to cut down on friendly fire against Bajoran comrades. After the end of the Occupation of Bajor, this feature fell into disuse.
Aboard Starbase Deep Space 9, Bajoran phaser weapons are regulated by the space station computer to setting 3, heavy stun, in order to prevent personnel violence and also to avoid damage to the station hull in case of misfires or abuse. (DS9 reference: Star Trek: Deep Space Nine Technical Manual)
Bajoran phaser rifles were used in a firing squad incident at Prison Complex 187 in the year 2368, in which a majority of a group of escaping condemned prisoners were killed, shot from behind as the war criminals tried to steal a Bajoran prison shuttle. (DS9 comic: "Turn of the Tide")
Militia troopers used these rifles when hunting down Shakaar Edon and the Shakaar resistance cell in the Dahkur Hills after the Shakaar associates resisted the authority of the government. (DS9 episode: "Shakaar")
The rifles seen in DS9 comic: "Turn of the Tide" may represent a variation in design, they had extended upper barrels and were gray, rather than the characteristic rust color of canon appearances of the weapon.
