The Magpul MAG592-BLK M-LOK 9-Slot Polymer Rail is a lightweight, cost-effective way to expand your mounting options on any M-LOK compatible handguard or forend. Whether you're adding a light, vertical grip, or other Picatinny-spec accessory to your rifle, this 4.1-inch rail section bolts directly to M-LOK T-nuts without requiring proprietary hardware or special tools. It's a practical choice for shooters who want flexibility without breaking the bank or adding unnecessary weight to their setup.
Built from Magpul's proprietary reinforced polymer composite, the rail delivers durability and strength while keeping things light. The injection-molded construction includes beveled ends that eliminate sharp corners and snagging hazards—details that matter when you're mounting and remounting gear or moving through brush. The design incorporates recoil and impact mitigation lugs to help absorb punishment and protect both the rail and your mounted accessories from unnecessary stress.
All mounting hardware is included, so you're ready to install straight out of the box on aluminum or polymer handguards alike. Made in the U.S.A., the MAG592-BLK comes in black and fits into any modern AR or other rifle system that uses M-LOK slots. If you're building or upgrading a rifle and want a straightforward, durable way to add tactical accessories, this is solid gear.
