Rail Rac Sandspear Holders keep your Sandspear held securely in place via BOTE's Rail Rac system. This new feature can be attached to the removable Slide Tracks that can be mounted to 6 different locations across the rails of the Rackham Aero. Plus, the Sandspear Holders can be converted to easily screw directly into the 1/4"-20 mounts located all along the rails of the Rackham Aero.
