Abstract: A rifle carrying case system. The rifle carrying case system includes a utility case for carrying rifles, a roller case for carrying rifle gear and accessories, and a docking station for mounting the utility case to a support structure such as a wall. The utility case and the roller bag case each include corresponding attachment mechanisms that enables the utility case to be removably coupled to the roller case for easy transit of the cases as a combined single unit. The attachment mechanisms include upper and lower hook members configured with the roller bag (e.g., with its extendable handle) and corresponding slots on the utility case that may be engaged by the hooks.
