WTS: Big Sky Inc. Skybar overhead gun rack. This rack allows you to carry two long arms in an overhead configuration in your car or truck. I used this rack to carry a shotgun and AR-15 rifle in my old SUV. My new truck will not permit the mounting of this type of rack. For more info see www.bigskyracks.com. These racks are attached with self-tapping sheet metal screws. All instructions and hardware included. You should make sure you have a double wall roof before you attempt installation.
