The Magpul MAG580-BLK M-LOK Aluminum Rail transforms any M-LOK compatible handguard into a versatile platform for accessories. This 3-slot rail section provides a secure Picatinny mounting surface exactly where needed without adding unnecessary weight or bulk to the entire system.
What Makes This Different
Unlike polymer rail sections that can flex under heavy accessories, this aluminum construction maintains zero shift under recoil and environmental stress. The precision-machined 6061-T6 aluminum provides the same strength as a full-length rail while weighing just 0.6 ounces. The beveled ends eliminate sharp edges that snag on gear or clothing during tactical movements.
Key Features
- 6061-T6 aluminum construction for maximum strength-to-weight ratio
- 3 Picatinny slots accommodate most standard accessories
- Direct M-LOK attachment system eliminates adapter plates
- Beveled profile reduces snag points and sharp edges
- Type III hard-coat anodized finish resists corrosion and wear
- Recoil lugs provide positive indexing and prevent movement
- Compatible with all M-LOK handguards and forends
Field testing demonstrates consistent zero retention through thousands of rounds across multiple calibers. The hard-coat anodizing withstands salt spray, humidity, and temperature extremes from -40°F to 140°F. Competition shooters rely on these rail sections for consistent optic and light placement, while law enforcement values the quick reconfiguration capability for mission-specific setups.
