The Area 419 Arcalock 12" M-LOK Dovetail Rail in Flat Dark Earth gives precision shooters a rigid, low-profile interface for bipods, tripods, and other Arca-style accessories. Machined from 6061-T6 aluminum with a Type 3 hard coat anodized finish, this 12-inch rail uses the Arcalock serrated dovetail pattern to mechanically lock into Area 419 clamps and reduce unwanted movement under load.

This model is designed to mount directly to handguards or chassis systems that offer six consecutive M-LOK slots, extending usable rail space along the full length of the forend while keeping weight to a minimum at about 4.1 ounces. It is well suited for precision rifle matches, prone or barricade shooting at the range, and any setup where quick accessory changes and repeatable positioning are important. Area 419 is known for clean machining, thoughtful design, and consistent quality across its Arcalock ecosystem.
