Device for attachment to a profiled rail

A device for selective affixation to a profiled rail, the device comprising:

• a. a body having an upper portion within which a profiled rail of a rail structure is receiveable;
• and,
• b. a clamp assembly operatively supported by said upper portion of said body, said clamp assembly characterized by an advanceable self-seating clamping block having a face comprised of upper and lower face portions, said upper face portion characterized by a profiled rail receiving segment, said lower face portion characterized by a longitudinally extending rounded protuberance, said longitudinally extending rounded protuberance delimiting a forward most extent of said face of said advanceable clamping block.

A clamp assembly for operatively uniting a platform of or for a weapon or weapon facsimile to a profiled rail of a rail structure in furtherance of reversibly securing the weapon or weapon facsimile to the profiled rail, the platform characterized by an upper portion comprising a first sidewall segment and a second sidewall segment, the second sidewall segment opposite and spaced apart from the first sidewall segment, the first sidewall segment having a profiled rail receiving surface, said second sidewall segment having a profiled free edge segment, the clamp assembly operatively supported by the upper portion of the platform and comprising a clamping block adapted for advancement toward the profiled free edge segment of the second sidewall segment from a biased condition with respect thereto, a lower portion of a clamping face of said clamping block pivotingly received by said profiled free edge segment of the second sidewall segment so as to self-seat said clamping block with a profiled rail interposed between the first sidewall segment and said clamping block of said clamp assembly upon advancement thereof.
