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 the lowest base fire rate. The Q-System's barrel will always grant it the "Cost-Effective" prefix, meaning it fires two bullets at the cost of one ammo, effectively doubling its damage output. 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.


  • The Q-System is obtained randomly from any suitable loot source.
