Q-System is the title of a group of common assault rifles in Borderlands 3 manufactured by Atlas.

Usage & Description

The Q-System has the highest base damage of all three Atlas assault rifles, and fires two projectiles at the cost of 1 ammo, offsetting its otherwise low fire rate. With no major penalties to its other stats, Q-System vastly outperforms other Atlas assault rifles and is one of the few common weapons able to compete with legendaries on higher difficulties.

Notable Variants

  • O.P.Q. SystemLegendary assault rifle that can deploy a miniature drone replica of the weapon that follows the wielder and fires at targets.


  • The Q-System is obtained randomly from any suitable loot source.
  • All Q-Systems come with the "Cost-Effective" prefix.
