Tracing its roots back to the respected and venerable Mossberg 500, the 590A1 keeps the core of what makes the 500-series of shotguns so great and makes it even better. The U.S. military put out a request for a more durable pump-action shotgun that could stand up to the rigors of hard field use, and the 590A1 was born. Mossberg responded by adding a tough parkerized finish,  all metal trigger guard, thick-walled barrel, and stronger internals. It is an intuitive and easy to use pump-gun, but it is a bit on the heavy side due to the aforementioned features. The extra weight helps tame the harsh recoil of the 12 gauge round, making the shooting experience a little more pleasant. The ambidextrous tang safety makes the gun easy for all users to operate the gun. Its wide aftermarket also allows you to tailor the gun to your specific wants and needs. While the 590A1 isn’t the smoothest or lightest shotgun out there, it is an absolute tank, and you’d be hard pressed to find any firearm that will last as long and take as much punishment.

The Mossberg 590 Mariner takes the standard tried-and-true 590 and adds an eye-catching corrosion-resistant Marinecote finish for those looking to fend off moisture and rust.
