Area 419 Firearms ARCALOCK 6" M-LOK Dovetail Rail FDE

The Area 419 ARCALOCK 6" M-LOK Dovetail Rail in Flat Dark Earth is a precision-machined accessory rail purpose-built for rifles and chassis systems that accept M-LOK attachment. At just 6" long and weighing only 2.2 oz, it adds an Arca-style dovetail mounting surface to the front of your rifle without piling on unnecessary weight.

Cut from 6061-T6 aluminum and finished with Type 3 hard coat anodizing for long-term durability and corrosion resistance, the ARCALOCK rail is engineered to handle real field abuse. The serrated rail sides interface with Area 419's proprietary clamp design to mechanically lock accessories in place, eliminating the play you can get from a plain lever clamp. The rail is cut to the RRS 1.5" dovetail standard, making it compatible with the broad range of Arca-Swiss lever clamps and quick-release systems on the market.

Designed with clean, snag-free ergonomics, the ARCALOCK features no sharp edges, so it sits comfortably under hand and won't catch on gear, packs, or slings. The rail requires 3 consecutive M-LOK slots on your handguard or chassis for installation, and all necessary M-LOK mounting hardware is included. Whether you are mounting a bipod, tripod clamp, ball head, or any other Arca-compatible accessory, the Area 419 ARCALOCK provides a rigid, repeatable platform that holds zero shot after shot.
