O.P.Q. System is a legendary assault rifle in Borderlands 3 manufactured by Atlas. It can only be obtained from enemies encountered in Revenge of the Cartels but has an increased chance to drop from Joey Ultraviolet in the Villa Ultraviolet.

Special Weapon Effects

B.Y.O.B.B. – Greatly increased stats. Fires 2 projectiles at the cost of 1 ammo. Occasionally causes a shock explosion on hit. Alternative Fire mode deploys a hovering drone replica of the gun which follows the wielder and fires at targets. Significantly slower alternate firing mode regeneration speed.

Usage & Description

The O.P.Q. System improves on the already impressive stats of a Q-System. Along with a high damage per shot and effective ammo use, the O.P.Q. System can further increase its damage output using its alternate firing mode, although it loses out the ability to track enemies with tracking rounds. Regardless, it is an incredibly powerful gun overall.

Care should be taken at close range, as the shock novas can easily down the user.


  • Drone weapons will benefit from anointed stats, even those that have specific conditions.


  • The weapon's name appears to be the shortened form of "Over-Powered Q-System". The Q-System is a common Atlas assault rifle that is renowned for being abnormally powerful for its rarity.
  • The flavor text is a reference to a scene from The Simpsons episode "Lisa the Vegetarian", where Homer Simpson prints invitations to a barbecue which reads "Come to Homer's BBBQ. The extra B is for BYOBB." While he notes the extra B in "BBBQ" is intentional, Homer reveals the extra B in "BYOBB" (Bring Your Own Bottle) is an actual typo.
