SKU: 419-ALK-CLAMP
Overview
Built for precision-rifle setups that use ARCA/1.5 dovetail rails, this clamp is intended to secure accessories with a mechanical lock rather than relying on friction alone. It offers compatibility with standard ARCA rails and can also be used with ARCALOCK rails for controlled movement and repeatable positioning. The design includes a two-stage screw system, a dovetailed moving side to help prevent tilt, and hardware intended to keep the clamp from coming apart if loosened too far. It is supplied as the clamp only, so it suits shooters who already have the rest of the setup and want a dedicated mounting solution.

Best Used For
- Hunters using ARCA/1.5 dovetail rails who want a mechanically locked clamp setup
- Precision rifle shooters needing quick rail adjustment without relying on friction alone
- Atlas bipod users seeking a clamp that bolts directly with factory hardware
- Users adding a barricade stop to an ARCALOCK-compatible support setup
- Shooters who want backwards compatibility with standard ARCA rails and infinite sliding adjustment

Pros
- Works on all standard ARCA/1.5 dovetail rails.
- Mechanical lock design adds detent engagement instead of friction alone.
- Proprietary two-stage screw offers fast movement and finer tension control.
- Backwards compatible with standard ARCA rails by removing the three pins.
- Dovetailed moving side helps prevent tilt during adjustment.
- Directly bolts to Atlas bipods using factory hardware on supported models.
Considerations & Trade-offs
- Works on standard ARCA/1.5 dovetail rails, but the ARCALOCK detent feature is what provides the mechanical lock; on a standard ARCA rail it functions as a sliding clamp rather than a locked interface.
- Barricade stop use is not universal: it can be used on the clamp with provided hardware, but it does not directly work with Harris bipods and requires a Barricade Kit for Harris compatibility.
- Direct Atlas bipod attachment is limited to models that use factory hardware; the 2-screw bipods need the Picatinny/1913 adapter.
- Includes clamp only, so bipod, barricade stop, and any other pictured items must be purchased separately.

Frequently Asked Questions
What rails does the Area 419 ARCALOCK Clamp fit?
It works on all standard ARCA/1.5 dovetail rails. The description also says it is backwards compatible with standard ARCA rails when the three pins are removed.
Does this clamp lock to the rail, or does it rely on friction only?
The product is designed to mechanically lock in place rather than rely on friction alone. On an ARCALOCK rail, it uses detents; on a standard ARCA rail, it can still be used after removing the three pins.
Can I use this clamp with an Atlas bipod?
Yes, it directly bolts to Atlas bipods using their factory hardware, except for the 2-screw bipods. For Atlas 2-screw bipods, a Picatinny/1913 adapter is available separately.
Will the barricade stop work with a Harris bipod?
Not directly. The description says the barricade stop does not directly work with Harris bipods, and that a Barricade Kit must be purchased for use with Harris bipods.
What comes in the package?
The package includes the clamp only. No bipod or other pictured items are included.
