The Mossberg 590 is a non-canon weapon featured in the Redux storyline, and made its first appearance in Kino Redux. It is the modern replacement for the Stakeout. It features ghost-ring rear sights that glow in the dark, making it excellent in the low-light conditions of the Basement. It is a one hit kill until Round 10. When Pack-a-Punched it becomes the 1337 M055B3RG 115, which gives it a Red Dot Sight, Grip, and Flashlight.
All Mighty Variant[]
In All Mighty, another 590 appears in Stainless Steel Finish. Called the 590 Mariner, this keeps the gun from rusting, and helps keep it from Jamming or Hang-Firing.
