Description
The Mossberg 590M 12ga 18.5in Tungsten Cerakote 10+1 is a mag-fed pump-action shotgun built for shooters who demand faster reloads and modularity without sacrificing the reliability of a pump. It ships with a 10-round detachable box magazine and a Magpul SGA adjustable stock, giving you a customizable length of pull and a solid cheek weld. The heavy-walled barrel and Tungsten Cerakote finish handle corrosion and wear, while the ghost ring rear and fiber-optic front sights get you on target fast.

Key Features
- Detachable Box Magazine: Why it matters – you reload in seconds, not one shell at a time, keeping you in the fight longer.
- Magpul SGA Adjustable Stock: Why it matters – you dial in length of pull for your build or gear, improving recoil control and shot consistency.
- Ghost Ring Rear & Fiber-Optic Front Sights: Why it matters – you acquire targets faster in low light or high stress, with a sight picture that works for slugs and buckshot.
- Optics-Ready Receiver: Why it matters – you mount a micro red dot directly (remove the cover plate) for precision at closer ranges without added rail height.
- Tungsten Cerakote Finish: Why it matters – you get a tough, low-glare coating that resists salt, sweat, and rough handling.
Who It’s For
This shotgun fits shooters who want pump-action reliability with mag-fed speed. It works for home defense setups where you need quick reloads under stress, for tactical shooters running courses, and for anyone who prefers a detachable magazine over a tube feed. If you already run AR-15s or other mag-fed platforms, the manual of arms translates easily.
Pros/Cons
- Pro: Magazine changes are fast and intuitive – you can carry spare 10- or 15-round mags on your vest.
- Pro: The Magpul stock gives you real adjustability, unlike most factory fixed stocks.
- Con: The 590M magazines are proprietary and cost more than standard tube-fed shell carriers. You’ll want at least two spare mags to get the full benefit.

FAQ
Does the Mossberg 590M accept standard Mossberg 500/590 barrels?
No. The 590M uses a heavy-walled 18.5-inch barrel designed for the mag-fed receiver. Standard 500/590 barrels are not compatible due to the different magazine and receiver geometry.
Can I use a pistol grip or aftermarket stock on the 590M?
Yes, the 590M accepts any stock or grip designed for Mossberg 500/590 receivers with the same tang-mounted safety. The included Magpul SGA can be swapped for a pistol grip or a fixed stock if you prefer.
What optics fit the receiver without an adapter?
The receiver has a factory-cut footprint for micro red dots like the Shield RMS, Holosun 407K/507K, and similar enclosed emitter sights. Remove the two screws and cover plate, then mount directly.
Is the 590M legal in all states?
Check your local laws. The 590M ships with a 10-round magazine, but higher-capacity magazines (15- and 20-round) are restricted in some states. The shotgun itself is a standard 18.5-inch barrel pump, so it generally meets federal and most state requirements for non-NFA firearms.
Last updated: April 2026
According to the National Shooting Sports Foundation, pump-action shotguns account for over 40% of all shotgun sales in the U.S. annually. The 590M gives you that proven action with a modern mag-fed twist.
