6 Rock Empire Robot cams. These cams are definitely a bit outdated, but they would make a serviceable backup rack for a beginner or something interesting for a collector. These cams should definitely be reslung before use as I could not work out the sling dates myself. I've had these for a little over two years now and used them a bit here and there as doubles to my main rack, but I am at the point of upgrading. Asking $120 shipped. Also open to local pickup in Fort Collins CO.
