Frequently Asked Questions

What types of ammunition can the Mossberg 590 SPX handle?

The 590 SPX is chambered for 3-inch 12-gauge shells, meaning it will reliably cycle both 2¾-inch and 3-inch loads. This includes standard birdshot, buckshot, and rifled slugs — making it versatile for home defense, range training, and hunting applications where legal.

What accessories can be mounted on the Picatinny rail?

The integrated Picatinny top rail is compatible with a wide range of tactical accessories, including red dot sights, holographic optics, magnified scopes, and rifle-style iron sights. Most standard MIL-STD-1913 rail-mount accessories will fit without modification.

How does the Mossberg 590 SPX differ from the standard Mossberg 590?

The 590 SPX (Special Purpose Xtreme) builds on the proven 590 platform by adding tactical enhancements such as the Picatinny top rail, an M16-style pistol grip stock, and a ghost ring rear sight with a front blade — features designed to give operators a more configurable and combat-ready package compared to the base 590 model.
