Area 419 ARCALOCK Dual-Clamp with Picatinny for Atlas Bipods

The Area 419 ARCALOCK Dual-Clamp with Picatinny for Atlas Bipods (stock code ARCALOCK Dual-Clamp) is a single lever clamp that mounts a no-clamp Atlas bipod to either an ARCA-Swiss dovetail or a 1913 Picatinny rail. An ON/OFF ARCALOCK switch engages or disengages Area 419's spring-loaded locking pins, so the same clamp can index positively on an ARCALOCK rail or clamp conventionally on a plain rail.

Atlas bipods leave the factory on a two-screw Picatinny mount, on an American Defense lever mount, or as an NC "No Clamp" body with no mount fitted. None of them is natively ARCA, so this is the clamp to buy if some of your rifles wear ARCA rails and others wear Picatinny and you want one bipod to serve them all.

How It Compares

This is the most versatile of the Area 419 clamps, and the heaviest. For ARCA only, the Area 419 ARCALOCK QD lever clamp is faster to fit and the Area 419 ARCALOCK knob clamp is lighter and lower. The Really Right Stuff BTC-Pro dual ARCA and Picatinny clamp covers the same two rail standards with a knob instead of a lever. For a Picatinny-only mount that also slides, see the Arisaka Picatinny rail slider. You will need an NC-bodied bipod such as the Atlas BT10-NC V8 from the Atlas bipod range, or a natively ARCA bipod from the Accu-Tac Arca-Spec range and our wider ARCA bipods.

Ideal For

• Shooters running one bipod across both ARCA-railed and Picatinny-railed rifles
• Practical and precision rifle competitors who borrow or swap rifles between stages
• Deer stalkers moving a bipod between a stalking rifle and a target rifle

Frequently Asked Questions

Does the Area 419 ARCALOCK Dual-Clamp really fit both rail types?
Yes. The Area 419 ARCALOCK Dual-Clamp has a jaw profile that clamps both ARCA-Swiss dovetails and 1913 Picatinny rails, so one clamp covers rifles built to either standard.

What does the ON/OFF ARCALOCK switch do?
The ON/OFF switch engages or disengages the spring-loaded ARCALOCK locking pins, so you can use the positive mechanical lock on an ARCALOCK-compatible rail and switch it off when clamping a plain rail.

Which bipods does the Area 419 ARCALOCK Dual-Clamp fit?
The Area 419 ARCALOCK Dual-Clamp fits NC "No Clamp" Atlas bipods, which are supplied by B&T Industries without a mount so that the buyer can choose their own clamp.

How does it compare with the Really Right Stuff BTC-Pro?
Both clamps cover ARCA-Swiss and 1913 Picatinny, but the Area 419 ARCALOCK Dual-Clamp uses a throw lever and the ARCALOCK locking-pin system, while the Really Right Stuff BTC-Pro is tightened by knob.

Are Atlas bipods ARCA without a clamp like this?
No. Atlas bipods are supplied with a two-screw Picatinny mount, with an American Defense lever mount, or as an NC "No Clamp" body, so ARCA mounting always comes from a separate clamp such as this one.
