TR-116

Memory Beta, the wiki for licensed Star Trek content.

The TR-116 was a rifle developed in the 2370s by Starfleet Security to operate in energy dampening fields or radiogenic environments, places where a phaser would not function. The rifle used tritanium bullets that were propelled chemically. Although design schematics were drawn up and replication patterns kept, the project was abandoned in favor of regenerative phasers. (DS9 episode: "Field of Fire")

In 2373, the USS Budapest was one of five test-bed starships that had TR-116 rifles aboard. When the Budapest engaged the Borg at the Battle of Sector 001, Sam Bowers and other crewmembers used the rifles against the Borg, killing many off them and stopping them from assimilating more members of the crew. Bowers had to also use the rifle to kill his assimilated crewmates, including Captain Sh'Raazn. (DS9 novel: Lesser Evil)

In 2375, Lieutenant Chu'lak, unstable due to the loss of his friends aboard the USS Grissom, replicated a TR-116 rifle on Deep Space 9. He also made modifications to it, adding a micro-transporter and an exographic targeting sensor device. He killed several crewmembers with the rifle before being stopped by Ezri Dax, who also used a TR-116. (DS9 episode: "Field of Fire")

The crew of the USS Enterprise used TR-116 rifles during their peacekeeping duties on Tezwa. They also used its sister weapon, the TR-120. (TNG novel: A Time to Heal)
