The Area 419 Arcalock 14.25" Universal Weight-Tunable Rail 419-ALK-14UNIV5WT brings the proven Arcalock dovetail system to a long, rigid accessory rail designed for precision rifle stocks. Machined from aluminum and finished in black hardcoat anodizing, it provides a mechanically locking interface instead of relying only on friction, giving bipods and supports a more repeatable, secure hold along the full 14.25 inch length.

This model is built to be as universal as possible while still allowing weight tuning with five removable brass weights, letting shooters fine tune rifle balance and recoil characteristics for disciplines like PRS-style competition or focused range work. It includes t-nut hardware for adding attachment points when factory inlets do not line up and can also interface with M-LOK systems when paired with separate hardware, reflecting Area 419’s attention to practical details and refined machining.
