The CAL (Cant And Loc) Atlas Bipods were developed for shooters that do not desire the Panning feature. The BT65-LW17 mounts directly to any 1913 style Picatinny rail via the included ADM-170-S Lever. It is comprised of 6061-T6 aluminum that is Mil-Spec Type III hard coat anodized and have heat treated stainless steel components. We chose to support a legend in the shooting sports by using the original KMW “Pod-Loc.” With the CAL bipod mounted to your rifle, you will be able to lock and un-lock the canting motion by rotating the Pod-Loc lever. Turn clockwise to lock and counter clockwise to un-lock. The Pod-Loc lever position can be adjusted for positioning by pulling the lever directly away from the body of the CAL and rotating to desired position. This positioning can be repeated until optimal position is achieved. Available in black only.
