The Magpul MAG590-BLK M-LOK 5 Slot 1913 Picatinny Polymer Rail is a lightweight, cost-effective way to add Picatinny rail real estate to your M-LOK-compatible handguard or forend. At 2.5 inches long, this injection-molded polymer section accepts standard Picatinny-mount accessories—tactical lights, vertical grips, laser units, or other rail gear—without eating up space or weight on your rifle. Whether you're building a modern sporting rifle, tactical carbine, or reconfiguring an existing platform, this rail adapter bridges the gap between M-LOK slots and your favorite Picatinny accessories.
Built from Magpul's proprietary reinforced composite, the rail delivers the strength you need without the heft of aluminum. Beveled ends reduce snagging and eliminate sharp corners that catch on gear or terrain. The design includes recoil and impact mitigation lugs to help absorb forces and protect your rail-mounted optics and accessories. All fasteners needed to mount directly to M-LOK-compatible T-nuts are included in the box—no hunting for metric screws or adapters.
Made in the USA, this polymer rail is a smart add-on for shooters who've standardized on M-LOK but still want the versatility of Picatinny attachment points. It's especially useful if you're upgrading an older polymer handguard to modern accessory standards or filling in gaps on a new build without committing to full-length rail sections.
