Area 419 ARCALOCK Spigot Extension


In stock

The ARCALOCK Spigot Extension was designed for use with Area 419’s ARCALOCK Clamp.

Some ARMS17-S accessory with matching hole pattern of 1.100” such as American Defense’s ADM-170-s, Arisaka’s Picatinny Rail Slider or Really Right Stuff’s BTC-Pro Bipod Clamp. However due to design, some clamps will NOT fit such as Magpul’s QR Rail Grabber (MAG1196) and Really Right Stuff’s SC-ARC Bipod Clamp.

It is ideal to adapt our BT35-NC 5-H Atlas Bipod to an ARCA clamp for clearance of the cradle and operation of the clamp’s knob. It will also extend all “NC” or No Clamp models (view complete list below) of Atlas Bipods out extra 1.25″ for increased stability. To use with your Bipod that already has a clamp, lever or mount installed, simply remove it to attach the spigot.

This spigot is manufactured by Area 419 NOT by B&T Industries L.L.C. Includes two 10-32 x 3/8″ flathead socket screws and two 10-32 x 5/8″ flathead socket screws.
