The Mossberg 590S Pump Action Shotgun offers the ultimate in shooting flexibility. This flexibility comes primarily from the 590S's ability to cycle 1.75″, 2.75″, or 3″ shells. Pick one shotshell length for specific shooting needs, or simultaneously load any combination of those shell lengths. The choice is yours with the 590S. The 590S also includes two new components not seen in previous models: a redesigned Elevator and Bolt Slide and an addition of an energy-absorbing Bumper. These components help to make the flexibility of shell length's possible. Along with these new components, you'll also get features that are standard for the 590. Standard 590 Pump-Action Features like: Dual extractors, twin action bars, positive steel-to-steel lockup, and anti-jam elevator provide smooth operation. Other features include top-mounted ambidextrous safety, matte blue metal finish, magazine clean-out tube with cap, and a logo-engraved receiver.
