Description
We stock the Mossberg 590S as a 12 gauge pump-action shotgun built around a 3-inch chamber. Its documented configuration includes compatibility with 1.75-inch, 2.75-inch, and 3-inch shells, along with ghost ring sights and a synthetic stock. The M-LOK (Modular Lock accessory mounting) forend provides an accessory mounting interface.

The fixed synthetic stock keeps the setup straightforward, while the ghost ring sights provide a clear sighting system without adding an optic. The cylinder bore choke and Accu-Choke system are listed as part of the configuration. The Mossberg 590S keeps its design focused on practical controls and useful included features.
