American Built Arms Company Polymer Picatinny Rail M-LOK 5-Slot

The American Built Arms Company Polymer Picatinny Rail is a lightweight 5-slot M-LOK accessory rail section engineered to add a continuous Mil-Spec 1913 Picatinny mounting surface to any M-LOK-compatible handguard. Machined from a technologically advanced, high-strength fiber-reinforced polymer, this rail is built to be light on the rifle and tough under fire, with excellent heat resistance for sustained use under lights, lasers, or other mounted accessories.

The polymer construction keeps overall weight to a minimum, while the continuous Picatinny slot pattern provides a solid, repeatable mounting platform for optics, red dots, back-up iron sights, lights, or laser units. Measuring 2.125" long with 5 usable slots, it is a compact, low-profile option for adding accessory real estate exactly where you need it on a modern sporting rifle equipped with M-LOK handguards.

Installation is straightforward: the rail attaches directly to M-LOK slots using the included M-LOK T-Nuts and 10-24 x 1/2" flathead screws, providing a secure, snag-free mount without requiring a separate rail section or adapter. Finished in Black to blend with most factory handguard surfaces, this is an ideal solution for shooters looking to expand their M-LOK platform with a dedicated Picatinny mounting point.
