The Area 419 Arcalock 14.25″ Universal Weight-Tunable Rail converts ARCA-style dovetail platforms into a mechanically locked mounting interface while providing onboard ballast options. It is engineered to fit a wide range of precision chassis and stocks and ships with five removable brass weights and T-nut hardware for added attachment points. The rail is finished in black hardcoat anodize and the included weights are raw brass. At .400″ thickness the 14.25″ Arcalock rail offers increased rigidity compared to AREA 419’s standard universal rails.
