Why the 590 Matters
Mossberg's 590 has been the choice of law enforcement and military units for decades. The 18.5" barrel strikes the perfect balance between handling and effectiveness. The cylinder bore gives you flexibility—use it with slugs for hunting or buckshot for home defense without changing barrels.
The FLEX system transforms the 590 from a one-size-fits-most gun into a truly personal shotgun. Whether you're a smaller-framed shooter, prefer a longer stock for hunting, or need a compact profile for tactical work, the adjustable stock adapts to you.
Built to Last
Synthetic construction throughout means this shotgun thrives in harsh conditions. The proven Mossberg action cycles everything from light target loads to heavy magnums without flinching. This is a shotgun that works.
