Magpul MAG494-ORG MOE M-LOK 12 Gauge Shotgun Forend for Mossberg 590/590A1 - Orange Polymer

The Magpul MOE M-LOK forend for Mossberg 590/590A1 shotguns is a drop-in replacement that turns your tactical or home-defense scatter gun into a more controllable, customizable platform. Built from orange polymer, this forend extends the grip zone and adds genuine modularity through its full M-LOK slot coverage—letting you bolt on lights, grips, slings, and other accessories exactly where you need them. Whether you're running your 590/590A1 for sport, home defense, or duty work, the MOE gives you the leverage and attachment points serious shotgun users expect.

The design includes front and rear hand stops that improve weapon control during transitions and manipulations—crucial when you're working fast or in tight quarters. It's lightweight, straightforward to install (drop-in fit, no gunsmithing required), and the orange polymer is durable enough for hard use while staying easy to locate in a bag or gear pile. The M-LOK ecosystem means your investment in this forend opens doors to years of accessory options.

Compatibility is straightforward: this forend fits Mossberg 590, 590A1, and compatible models with 7-5/8" action tube assemblies. It will not fit the shorter 6-1/2" tubes found on some Mossberg 500 variants, nor the pinned-in synthetics on current production Mossberg 500 models without an action tube swap. Confirm your shotgun's tube length before ordering.

Frequently Asked Questions

Will this Magpul forend fit my Mossberg 500?

No, not without modification. The MOE M-LOK forend fits Mossberg 590 and 590A1 shotguns with 7-5/8" action tube assemblies. Mossberg 500 models with 6-1/2" tubes, or current-production synthetics with pinned-in action tubes, require the 7-5/8" assembly replacement before this forend will fit. Confirm your gun's action tube length before ordering.

What M-LOK accessories can I attach to this forend?

Any M-LOK-compatible accessory works with this forend. That includes tactical lights, hand stops, slings, rails, grips, and other modular gear designed to the M-LOK standard. The forend features M-LOK slots on the front and sides, giving you flexibility in how you configure your shotgun.

Is this a bolt-on installation, or do I need a gunsmith?

It's a drop-in replacement requiring no gunsmithing, special tools, or professional installation. You simply swap out the original forend for this one.

Why orange polymer?

The orange color provides high visibility for finding and identifying the shotgun in gear bags or low-light conditions. Magpul polymer is proven for durability and stands up to hard field use.
