History and specificationsEdit
It fired adhesive projectiles that would deliver a non-lethal shock that would incapacitate the Jem'Hadar soldier for an hour. The rifle was practically silent and had no muzzle flash or other visible effect, and thus was ideal for stealth combat situations.
In the year 2379, the crew of the USS Enterprise used TR-120 rifles, as well as TR-116 rifles, against Kinchawn's rebel Tezwan fighters during their peacekeeping duties on Tezwa. (TNG - A Time to... novel: A Time to Heal)
