Rotapoint Systems LLC has a quick presentation of their new Rotapoint Offset Red Dot Mount... "We developed the world's first cantilever-clamping offset mount as a faster, stronger, and more ergonomic solution than the rail-mounted ones already available.  A slight turn of the wrist quickly brings your red dot into view with no head movement.  Models are available for both ADM and LaRue cantilever mounts, and RMR, DPP, and Aimpoint Micro footprints.
