The Area 419 Arcalock QD Clamp adds a 3-position lever-release design to the ARCALOCK family of dovetail mounting hardware. The reversible lever arm is milled from stainless steel, letting shooters choose between a clamped, sliding, or fall-off setting depending on the accessory.

It uses the widely supported 17S mounting footprint, so it works with existing Atlas and Thunderbeast bipod adapters and similar accessories already on the rail. A steel adjustment knob is built in for long-term reliability, and the pins are removable for use with any standard ARCA rail.

Frequently Asked Questions

Will this clamp fit my existing ARCA rail? Yes. The ARCALOCK pins are removable, so the clamp can be used on any standard ARCA rail in addition to Area 419’s own ARCALOCK rails.

Does it work with the RCX Gen 2 bipod? No. Area 419 notes the lever cannot fully actuate on RCX Gen 2 – check compatibility before ordering if you run that bipod.
