Area 419 Arcalock 12" Universal Dovetail Rail
$100.00
The Area 419 Arcalock 12" Universal Dovetail Rail is a precision accessory rail built for shooters who demand rock-solid stability on their precision rifle setups. Designed to work with Arca-Swiss compatible clamps and lever systems, this 12-inch rail mounts to the front of your rifle stock or chassis to give you a full length of real estate for bipods, bags, and other support gear. It's engineered around the RRS 1.5" dovetail standard, so your existing lever clamps will lock down tight—and stay locked.
What makes the Arcalock different is the serrated side interface that works with Area 419's proprietary clamp design to mechanically lock the rail in place with zero movement. Those serrations are blunt by design—they grip without cutting your hands or marring gear bags. The rail itself is backwards compatible with standard Arca accessories, though you'll get that signature positive lock only when paired with Area 419 clamps. At just 4.1 ounces, the weight penalty is negligible even on weight-conscious builds.
Built in the USA from 6061-T6 aluminum and finished with Type 3 hard coat anodize, this is a rail made to handle field use. Every corner is radiused and edge is chamfered—a detail that takes longer to machine but eliminates snag points and rough surfaces. Installation uses your rifle's front action screw attachment point and can anchor at up to four locations for maximum rigidity. The kit includes an extended-length Remington 700-style action screw (trimming may be required to fit your rifle) plus tee nuts and hardware; a 3/4" paddle bit and drill press may be needed depending on your current setup.
Originally designed with Manners composite stocks in mind, the Arcalock works with any rifle and stock configuration that has an accessible front action screw and attachment point(s). Whether you're running a precision chassis, a custom composite stock, or a factory rifle with the right geometry, this rail delivers a clean, lightweight way to mount support gear without compromise.

Frequently Asked Questions
Will this work with my existing Arca-Swiss lever clamps?
Yes. The Arcalock is designed to the RRS 1.5" dovetail standard, so commercial lever clamps will fit and function. However, you'll get Area 419's signature mechanical lock (no movement) only when using their proprietary clamp design. Standard Arca accessories will mount but without the anti-rotation locking feature.
What stocks and rifles is this compatible with?
The Arcalock is designed to work with any rifle and stock configuration that has an accessible front action screw and a front attachment point or points. It was originally developed for Manners composite stocks but accommodates a wide range of chassis systems and aftermarket stocks. Your gunsmith or stock manufacturer can confirm fitment on your specific setup.
What hardware and tools do I need to install this?
The rail comes with an extended-length Remington 700-style action screw (trimming may be required to fit your rifle), tee nuts, and mounting hardware. Installation at the front action screw is straightforward. Depending on your current rifle configuration, you may need a 3/4" paddle bit and drill press to install tee nuts. MLOK hardware is not included.
Is the rear barricade stop included?
No. The rear fixed barricade stop is sold separately and is not included with this rail.
