The Area 419 419-ALK-MLOK12 Arcalock 12" M-LOK Dovetail Rail brings a rock-solid, mechanically locking interface to modern precision rifles. Precision machined from 6061-T6 aluminum and finished with a Type 3 hard coat anodize, this 12-inch rail follows the RRS 1.5" dovetail standard while adding Area 419’s serrated Arcalock profile for secure, repeatable accessory mounting along the full length of your forend.

Designed to attach using six consecutive M-LOK slots, this rail is ideal for shooters who rely on bipods, barricade stops, and tripods for stable shooting positions. The smooth serrations lock into the matching Area 419 clamp to prevent unwanted movement under load, yet remain comfortable on bags and in the hand. Backwards compatibility with standard Arca accessories, included M-LOK hardware, and thoughtful edge chamfering make this rail a refined upgrade that reflects Area 419’s reputation for careful engineering and clean machining.
