This is a simple part that is needed to attach a secondary sight to your C1 mount in an angled fashion. With the Condition 1 mounting system, Badger has made the mount very modular, and you pick and choose the parts you need.
The Condition One J-Arm allows a variety of accessories to be mounted directly to the Condition One Modular Mount (C.O.M.M.). The J-Arm can be mounted left or right, fore and aft, allowing the operator to determine the optimized location for their application.
The J-Arm comes in Tan and Black (offered here), and in both 35 degree and 45 degree angles for either 1.70" or 1.93" scope heights.
