Frequently Asked Questions

Will this clamp work with every ARCALOCK accessory?
Not quite — Area 419 notes the added width of this Dual-Clamp makes it incompatible with a few devices, including the Garmin Xero and certain Arms RailChanger X products, so confirm fitment with your specific accessory first.

What bipods can I attach through the ARMS 17S interface?
Common bipods from Atlas, Thunderbeast, MDT, Magpul, and Harris (with an adapter) are all compatible.
