Badger Ordnance's Condition One Accessory Ring Cap or C1 ARC delivers greater options for customization on any of the Condition One Modular Mounts. The C1 ARC can be attached on either the fore or aft on the C1 Mount, and allows a multitude of accessories to be installed, such as laser range finder rails or 12 o'clock mounted red dot optics. These accessories can be attached/detached without having to remove the ARC, allowing the primary optic to retain the original zeroing.
