Citadel Mariner 12 Gauge Pump-Action Shotgun, 18.5″ Barrel

Product Description

The Citadel Mariner is a 12 gauge pump-action shotgun with an 18.5″ barrel. It has a 3″ chamber and a tubular magazine that holds 4+1 rounds. The finish is matte black, and the stock is black synthetic.

A few features set it apart from a bare-bones pump gun. It comes with a heat shield over the barrel and a side shell holder on the receiver. The sights are blade style and adjustable. A Picatinny rail with a 0 MOA base sits on top, so you can mount an optic without drilling or adding an adapter. The firing system uses an internal hammer.

Who it suits

The short barrel and 13.6″ length of pull make this a handy size for home defense. It also works as a general-purpose field gun for clearing a property or practicing at the range. Pump action keeps the controls simple, and you cycle each round by hand.

Gear that pairs well includes a red dot or other optic for the rail, a sling, extra shell carriers, and a set of snap caps for dry practice. Because the chamber takes 3″ shells, you can also run shorter shells in it. Pick your load for the job you have in mind.
