Magpul MAG478-BLK M-LOK to MOE Adapter Kit - Black
- Firearm Group:
- AR Platform
The Magpul MAG478-BLK M-LOK to MOE Adapter Kit is a practical solution for shooters who want to use their modern M-LOK accessories on older MOE handguards and forends. If you've built an AR with legacy Magpul MOE furniture but your accessory collection has shifted toward M-LOK compatibility, this kit bridges that gap without forcing a handguard swap. It's a smart way to extend the life of proven handguards while staying current with your optic rails, tactical lights, and rail-mounted gear.
The adapter plates themselves are modular—you can customize their length by snapping off sections at pre-scored break points. That flexibility means you're not forced to use a one-size-fits-all solution; you can trim the adapter to fit your specific MOE handguard and accessory mounting position. All the hardware you need is included in the box, so there's no hunting for fasteners.
Built in the USA and backed by Magpul's reputation for robust polymer design, this adapter kit works with most Magpul M-LOK compatible accessories. Whether you're upgrading a hunting rifle, a precision range gun, or a tactical build, this is a no-fuss way to make your newer gear play nicely with your existing handguard investment.
