Key Features

Dual Action Bars: Why it matters — prevents binding when cycling the action, so the gun feeds and ejects reliably even when you’re working the pump fast.
18.5-inch Barrel with Cylinder Bore: Why it matters — gives you a wide, forgiving pattern at close range, exactly what you need for home defense without over-penetration worries.
ODG Synthetic Furniture: Why it matters — resists moisture and impacts, keeps the gun lightweight and easy to shoulder for smaller shooters.
6+1 Capacity: Why it matters — seven rounds on tap gives you enough firepower to handle multiple threats or extended practice sessions without constant reloading.
Ambidextrous Safety: Why it matters — lefties and righties can both reach the tang safety quickly, no fumbling under stress.

Who It’s For

This shotgun fits families who want one gun for the nightstand and the range. It’s simple enough for a new shooter to learn on — pump action means you control the pace — but tough enough for seasoned shooters who need a reliable tool. The ODG finish blends in with outdoor gear, so it works for truck guns or camp protection too.

Lightweight at under 7 pounds, easy for youth shooters to handle

The 590R costs more than the Maverick 88 and Remington 870 because of its parkerized finish, higher capacity, and dual-action bars. If you want a gun that can handle thousands of rounds without rusting, the 590R is worth the premium. The 870 is lighter on the wallet but heavier in the hand and has a lower capacity.

FAQ

What shells does the Mossberg 590R accept?

It cycles 2.75-inch and 3-inch 12-gauge shells. Stick with 2.75-inch for range practice; 3-inch magnums are fine for hunting or defense if you can handle the recoil.

Can I mount a red dot on the 590R?

The receiver is drilled and tapped for a scope base or rail. You’ll need to buy a Picatinny rail adapter separately. No ghost rings come standard, so plan on adding those if you want them.

Is the 590R compatible with aftermarket stocks?

Yes, it uses the standard Mossberg 500/590 tang safety system. Any stock made for the 500 series (like Magpul or Hogue) will fit.

How do I clean the parkerized finish?

Wipe it down with a light oil after shooting. Parkerized metal is porous, so it holds oil well — that’s what protects it. Avoid harsh solvents that strip the oil.

What is the difference between the 590R and the regular 590?

The 590R has a shorter magazine tube (6+1 instead of 8+1 or 9+1) and a lighter barrel profile. It’s designed for easier handling and quicker shouldering, while the standard 590 is built for higher capacity and military contracts.
