The Magpul MAG582-BLK M-LOK Aluminum Rail transforms any M-LOK compatible handguard into a versatile mounting platform for accessories. This 7-slot rail section provides the Picatinny real estate needed for lights, grips, and other tactical equipment without adding unnecessary weight to the firearm.
What Makes This Different
Unlike polymer alternatives, this aluminum construction delivers military-grade durability while maintaining a low profile. The precision-machined surface ensures consistent return-to-zero for optics and accessories. At just 1.2 ounces, it adds minimal weight compared to full-length quad rails that can exceed 12 ounces.
Key Features
- 7 Picatinny slots provide 3.5 inches of accessory mounting space
- 6061-T6 aluminum construction with Type III hard coat anodizing
- Direct M-LOK attachment system eliminates wobble and maintains zero
- Beveled edges prevent snagging on gear and clothing
- Recoil lugs distribute stress across multiple mounting points
- Compatible with all M-LOK handguards and forends
- Includes stainless steel M-LOK hardware and installation tool
Field testing demonstrates this rail section maintains zero through thousands of rounds across multiple calibers from 5.56 NATO to .308 Winchester. The hard anodized finish resists corrosion in marine environments and extreme temperatures. Competition shooters rely on its consistent return-to-zero when removing and reinstalling accessories between stages.
