Area 419 ARCALOCK 12″ M-LOK Dovetail Rail

The Area 419 ARCALOCK 12" M-LOK Dovetail Rail provides a locking ARCA dovetail interface designed for precision and modularity on compatible rifle forends. It installs via M-LOK and gives full-length attachment space while remaining lightweight in profile. Note that the ARCALOCK system mechanically locks only when used with an Area 419 clamp.
