Area 419 Firearms ARCALOCK 12" M-LOK Dovetail Rail

The Area 419 ARCALOCK 12" M-LOK is a universal accessory rail that mounts to any M-LOK compatible handguard, giving you the full length of the forend for optics, lights, lasers, and other accessories. The rail is machined from 6061-T6 aluminum in-house by Area 419 and features serrated rail sides that interface with the proprietary ARCALOCK clamp design to mechanically lock the rail in place so no movement is possible once installed.

At a full 12 inches long and weighing only 4.1 ounces, the ARCALOCK delivers a long, stable mounting platform without adding meaningful weight to your rifle. It attaches at up to 4 mounting points for maximum strength and stability, and requires 6 consecutive M-LOK slots on your handguard for proper fitment. The rail is also backwards compatible with previous ARCALOCK clamping hardware.

Whether you are building a precision rifle, a hunting setup, or a tactical rig, the ARCALOCK 12" M-LOK provides a solid, repeatable accessory mounting solution that will not shift under recoil. Proudly Made in the USA by Area 419.
