Area 419 ARCALOCK Clamp and Barricade Stop Kit

Product Description

Precision Contact with the ARCALOCK Clamp and Barricade Stop Kit

The ARCALOCK Clamp and Barricade Stop Kit works seamlessly with all standard ARCA/1.5″ dovetail rails.

Use it on its own as a barricade stop or pair it with an Atlas bipod for even more versatility.

Area 419 engineered this kit to fix a common problem—friction-based clamps that shift under pressure. Traditional ARCA rails can’t always hold up in tough conditions. This system locks mechanically into place, ensuring zero movement when it counts.

Designed for Performance and Compatibility

The ARCALOCK Clamp and Barricade Stop Kit features a proprietary two-stage screw. It starts with a coarse 16 TPI thread for quick positioning. Then, under tension, it transitions to a fine 32 TPI thread for extra torque and holding power.

• About a quarter-turn releases the clamp from ARCALOCK detents

• One full turn removes it completely from the rail

• Compatible with Atlas Bipods (QD and NC models only) using their factory hardware

• Works with Atlas 2-screw bipods using the Picatinny/1913 Adapter

• Use the barricade stop alone or sandwich it between an Atlas bipod

• Requires additional kit for use with Harris Bipods

Built to Lock and Last

The ARCALOCK Clamp and Barricade Stop Kit adapts to standard ARCA rails by removing the three locking pins. This allows infinite sliding adjustment when needed. Its dual-sided dovetail design prevents tilt, while the unique knob and screw keep the clamp from coming apart during use.
