The Area 419 ARCALOCK 12" Universal Dovetail Rail from Area 419 Firearms LLC delivers a lightweight, durable solution for precision setups, with a 12" length that spans the entire stock forend while weighing just 4.1 oz, making it ideal for versatile attachment configurations. Its serrated rail sides interface with a proprietary clamp design to mechanically lock the rail in place so no movement is possible, and the radiused edges and chamfered corners ensure smooth handling and safe bag engagement. Made from 6061-T6 aluminum and finished in Type 3 hard coat anodize for enhanced durability, this rail is backward compatible with standard Arca accessories while requiring our clamp to achieve locking security. Designed to attach to the rifle at up to four points for maximum strength and stability, it accommodates a multitude of rifle and stock configurations that feature an accessible front action screw and a front attachment point, with Manners Composite Stocks as a common consideration. It follows the RRS 1.5" dovetail standard to ensure lever clamps work reliably, and it includes Remington 700-style extension hardware with tee nuts and necessary hardware, though some trimming may be required depending on the rifle, and a 3/4" paddle bit and drill press may be needed for tee-nut installation. Rear fixed barricade stop is not included, and MLOK hardware is not included.
