The Area 419 Arcalock 6" M-LOK Dovetail Rail FDE gives precision shooters a rock-solid, repeatable interface for tripods, bipods, and other Arca-style accessories. Machined from 6061-T6 aluminum and finished in a flat dark earth Type 3 hard coat anodizing, this 6-inch rail uses serrated sides that mate with the Arcalock clamp to mechanically lock in place and prevent unwanted movement under load.

This compact rail requires three consecutive M-LOK slots and arrives with all necessary mounting hardware, making it an easy upgrade for chassis and handguards that support the M-LOK standard. Built to the RRS 1.5" dovetail specification, it remains backward compatible with standard Arca accessories while offering enhanced security when paired with the Arcalock clamp. It is an excellent choice for competition, long-range practice, and field shooting where stable, repeatable positioning matters. Area 419’s precise machining and thoughtful design are evident in the smooth radiused corners, chamfered edges, and overall fit and finish.
