Mossberg 590S Pump-Action Series Gets Two Optic-Ready Models

The only thing that beats a shotgun for home defense is a shotgun with an optic for home defense. While you may be on the fence about optics on a shotgun, they are becoming increasingly popular. This is because, like any firearm, they help with rapid target acquisition. And now, the popular 590S pump-action shotgun series from Mossberg adds two optic-ready options, making a great shotgun even better.

Mossberg Optic-Ready 590S Pump-Action Series Shotguns

New to the 590S Pump-Action Series lineup are two optic-ready options. Available in 18.5-inch or 20-inch, the shotguns are ready to accept the direct mount of red dot sights out of the box. Utilizing the Shield RMSc footprint, the optics-ready options come with a cover plate for when a sight is not mounted.

The 18.5-inch model features a cylinder bore barrel with a front bead sight and corncob forend. Similarly, the 20-inch model features an AccuChoke-compatible barrel (Cylinder choke tube included), front bead sight, and M-LOK compatible forend. Each model is available with an MSRP of $704.00.

Out of the 590S lineup, these are the only two with optic-ready capabilities. So, the Shockwave models are not included in the current optic-ready availability. Whether that will change down the road remains to be seen.

Editor’s Note:

When deciding on a red dot sight for your shotgun, consider one with a ring/dot reticle. When using a ring/dot reticle, the ring acts as a makeshift bracket for the shotgun’s spread at distance.

Besides optic-ready compatibility, the two new models feature the same specs and functions as the rest of the line. Please check out the original story below for more details.

On February 8, 2022, PDW reported:

Known for high-quality shotguns, Mossberg offers the ultimate in shooting flexibility with the 590S Pump-Action Series. Specifically, the series can cycle any combination of 1.75-inch, 2.75-inch, or 3-inch shells, right out of the box. As a result, you can pick one shotshell length for specific needs, or simultaneously load any combination of shell lengths.

The Mossberg 590S Pump-Action Series

Available in four different models, the 590S series offers two full-length stocks or two compact Shockwave-gripped models. The full-length stocks are available paired with an 18.5-inch barrel with bead sight or a 20-inch barrel with adjustable ghost ring sights and M-LOK compatible forend for optics or accessories.

Comparatively, the Compact models are available with your choice of 14.375-inch or 18.5-inch barrel. Both Compact models feature bead sights.

“You might recognize this. This is the Mossberg 590 pump-action shotgun, over 12 million in production. A lot of you are probably familiar with it but there is something very different about this one. You’ll notice that it says 590S. The S stands for Shorty. This gun is now capable of handling the mini shells, the inch and three-quarter, two and three-quarter inch, and three-inch shells interchangeably, without the use of an adapter,” said Mossberg Representative, Linda Powell.
