Area 419
The Area 419 Arcalock 14'' Universal Dovetail Rail brings mechanical locking to precision rifle accessory mounting. Unlike traditional friction-fit ARCA rails that can shift under load, the Arcalock system uses proprietary serrated sides that interface with Area 419 clamps to lock your rail solidly in place with zero movement. If you've watched a barricade stop creep during a string of fire or adjusted your bag stop mid-session, you'll appreciate the confidence that comes with 65 distinct locking positions across the 14-inch length.
This rail is built as a universal solution for rifle and stock configurations with an accessible front action screw and forward attachment point. The 14-inch length spans the entire forend of most modern stocks, giving you maximum real estate for bipod placement and other attachments—and because it extends past the stock, you can mount your bipod farther forward for additional stability. The design accommodates up to four attachment points for maximum strength and is backward compatible with standard ARCA accessories (though locking function requires an Area 419 clamp). A serrated fixed rear barricade stop comes standard, plus an extension plug to raise it an additional half-inch if needed. At 156 grams, the rail adds minimal weight to your system.
Built in-house on USA-made CNCs from USA-sourced 6061-T6 aluminum, the Arcalock is finished in Type 3 hard-coat anodize for durability in field use. Every edge is chamfered and corner radiused—a manufacturing detail that matters when you're working around the rail for hours. The rail comes with one extended-length Remington 700-style action screw for the front attachment point; some trimming may be required depending on your specific stock and chassis. Spacers are available separately if your rifle has a non-flat forend.
| Length | 14 inches |
| Weight | 156.03 grams |
| Material | 6061-T6 aluminum |
| Finish | Type 3 hard-coat anodize |
| Dovetail Standard | RRS 1.5-inch (standard lever clamp compatible) |
| Locking Positions | 65 |
| Included Hardware | One extended-length Remington 700-style action screw, tee-nuts, hardware |
| Locking Function | Requires Area 419 clamp |
The rail is backward compatible with standard ARCA accessories and will accept them physically. However, the locking function—the mechanical advantage that prevents movement—only works with Area 419 clamps designed for the serrated rail sides. Without an Area 419 clamp, you're relying on friction fit like a traditional ARCA rail.
The Arcalock is a universal solution designed to fit most rifle and stock configurations that have an accessible front action screw and some form of forward attachment point. It was designed with Manners Composite Stocks in mind, but works across many chassis and stock types. If your rifle has a non-flat forend, spacers are available separately to accommodate the difference.
The rail comes with one extended-length Remington 700-style action screw for the front attachment point, tee-nuts, and necessary hardware. M-LOK hardware is not included. Some trimming of the action screw will likely be required depending on your specific stock and chassis combination.
Yes. The 14-inch rail extends past the end of most rifle stocks, allowing you to attach your bipod farther forward than you could on the stock alone. This increases stability, particularly valuable for precision shooting from field positions.
