The Magpul MOE M-LOK Forend is a replacement pump forend for Mossberg 590 and 590A1 12-gauge shotguns, with M-LOK slots molded in.
The Magpul MOE M-LOK Forend for Mossberg 590/590A1 (MAG494) upgrades the most important contact point on a pump shotgun. Integrated M-LOK slots let you mount a weapon light, hand stop or sling point directly to the forend — the correct position for a defensive shotgun — while the aggressive texture and front/rear hand stops keep the pump stroke positive when hands are wet, cold or gloved.
Molded from Magpul's reinforced polymer, the forend adds capability without fragility, and its extended profile improves leverage on the action tube for faster, more decisive cycling. For 590-series guns in service or by the bed, this is the upgrade that matters most.
Key Features
- Integrated M-LOK slots: direct mounting for lights and accessories
- Front & rear hand stops: a planted pump hand under recoil
- Aggressive no-slip texture: control in any conditions
- Reinforced polymer shell: service-grade durability
- Four finishes: Black, Flat Dark Earth, Stealth Gray, Orange
Compatibility & Fitment
A direct replacement for the factory forend on Mossberg 590 and 590A1 12-gauge shotguns. It is not intended for the 500, which uses a different action bar arrangement, so check which model you have before you buy. Factory forend removal needs a forend wrench or a gunsmith; fitting the MOE from there is straightforward, with no permanent alteration to the shotgun.

Frequently Asked Questions
Will this forend fit my Mossberg?
The MAG494 is a direct replacement for the factory forend on Mossberg 590 and 590A1 12 gauge shotguns. It is not intended for the 500, which uses a different action bar arrangement, so check which model you have before you buy. If your gun has been modified or you are unsure of the variant, get in touch with the model details.
What do the M-LOK slots let me add?
The forend has M-LOK slots molded directly into the body, so lights, sling mounts and hand stops can be attached without a bulky rail system hanging off the gun. Accessories bolt straight to the slots using M-LOK hardware, which keeps everything close to the barrel line. If you own Picatinny-mount accessories, you can fit an M-LOK Picatinny rail section rather than replacing them.
What is it made from and how does it fit?
It is a reinforced polymer molding, so it stays light and is comfortable to hold even after a string of shots has warmed the magazine tube. Fitting is a straightforward swap of the factory forend on the action bars, and no permanent alteration to the shotgun is involved. Work carefully and support the action bars while the forend is off.
Which colors are there, and does it pair with a stock?
Black, Flat Dark Earth, Stealth Gray and Orange are offered, with Orange often chosen for training or clearly marked guns. It pairs naturally with the SGA stock if you want to change both ends of the shotgun at once.
