1. A kinematic coupling mounting device for mounting an ancillary device to a firearm, the mounting device comprising:
an ancillary device frame mounted to the ancillary device; a firearm frame mounted to the firearm; a first projection and a first receiver, the ancillary device frame including the first projection and the firearm frame including the first receiver, the first receiver configured to engage the first projection and restrict motion of the first projection in at least one degree of freedom; a second projection and a second receiver, the ancillary device frame including the second projection and the firearm frame including the second receiver, the second receiver configured to engage the second projection and restrict motion of the second projection in at least one degree of freedom; a third projection and a third receiver, the ancillary device frame including the third projection and the firearm frame including the third receiver, the third receiver configured to engage the third projection and restrict motion of the third projection; wherein the first, second and third projections are mounted in a triangular configuration and the internal angles of the triangular configuration at the first and second projections are substantially equal; wherein the firearm frame includes a top surface and a side surface substantially perpendicular to the top surface, the top surface including the third receiver and the side surface including the first and second receivers; and the ancillary device frame includes a top surface, a first support arm and a second support arm, the top surface including the third projection, the first support arm including the first projection and the second support arm including the second projection; and wherein the ancillary device frame and the firearm frame can be coupled and decoupled repeatedly, and each time the ancillary device frame is coupled to the firearm frame, the first, second and third projections and the first, second and third receivers cause the ancillary device frame and the firearm frame to have the same orientation and position with respect to each other, the ancillary device frame and the firearm frame not being adjustable relative to one another when coupled. |
