The tri-beam laser rifle is a weapon in Fallout: New Vegas.


The tri-beam laser rifle has the appearance of a "sawed-off" laser rifle, missing the tube on the bottom length of the barrel, being rather shorter than other models, and having a new emitter aperture and attached wires. The new emitter fires three laser beams with each shot. While uncommon in the wasteland, it can be readily found with the New Vegas Brotherhood of Steel. It uses 3 microfusion cells when fired. This weapon degrades very quickly and is very expensive to repair. With the Jury Rigging perk it can be repaired with regular laser rifles.

Due to the fact that it fires three beams at once, it can score a critical hit for each beam outside of V.A.T.S. This results in the weapon occasionally dealing huge amounts of damage.


The tri-beam laser rifle degrades rapidly, as it can only fire a total of about 245 times using standard cells, the equivalent of 31 reloads, from full condition before breaking.

  • The tri-beam laser rifle boasts a greater damage per second and critical hit multiplier when compared to its plasma equivalent, the multiplas rifle. However, the tri-beam laser rifle is heavier, and much more expensive to repair.
  • As with the multiplas rifle, use of over charge or max charge microfusion cells allows the weapon to overcome its flaws against most armored targets, but the increased degradation effect is also applied for each shot.
