Citadel Mariner 20 Gauge Pump-Action Shotgun, 18.5″ Barrel

Product Description

The Citadel Mariner is a 20 gauge pump-action shotgun with an 18.5″ barrel. It holds 4 rounds. The manufacturer part number is FRMN2020NKL, which helps if you are matching it to a specific order or a dealer record.

Pump action is the simple, familiar way to run a shotgun. You work the forend by hand to eject the spent shell and chamber the next one. There is no gas system to tune and nothing to set between loads. The short 18.5″ barrel keeps the gun easy to turn in tight spaces, such as a hallway, a truck cab, or thick brush.

Who the Mariner suits

This shotgun fits a buyer who wants a compact 20 gauge with a pump action. It works for a home-use gun, a utility gun to keep handy around a property, or a first shotgun for someone learning manual operation. Because you cycle it yourself, it also makes a good platform for practicing smooth, deliberate gun handling.

Gear that pairs well with it includes 20 gauge shells for your intended use, a sling, a shell holder for extra ammunition, and a padded case for transport. Eye and ear protection are a must at the range. A basic bore brush and cleaning kit will keep the action running smoothly.
