The Magpul MAG580-BLK M-LOK 3 Slot 1.6" Aluminum Rail is a compact accessory rail built for shooters who need precise mounting options on M-LOK-compatible handguards and forends. If you're running an AR or other tactical rifle with M-LOK slots and want to add a light, vertical grip, or other Picatinny-spec rail gear without cluttering your entire setup, this short rail section gives you exactly what you need in a clean, lightweight package.

Machined from milspec-anodized aluminum, this rail is built tough and designed to take hard use. Magpul engineered it with beveled ends to keep things snag-free and smooth—no sharp corners catching on your gear or gear bag. The hardware you need to bolt it directly to either aluminum or polymer M-LOK handguards comes in the box, so you're ready to go straight out of the package.

The three Picatinny slots give you solid mounting real estate for your choice of accessories. Magpul also incorporated cammed T-nuts and recoil/impact mitigation lugs to keep your mounted gear stable and absorb shock from firing. At 1.6 inches overall length, it's compact enough to fit tight spaces without adding unnecessary weight or bulk to your rifle.

This is genuine Magpul engineering, made in the USA. It's a no-fuss, proven component for rifle builds and upgrades that demand reliability.
