Sensor system for advanced smart weapons barrels

A smart barrel system for a firearm, comprising:

• a first barrel segment and a second barrel segment, each barrel segment comprising a tubular member having an axial bore, a proximal end, and a distal end;
• the proximal end of the first barrel segment having a first threaded element for removably attaching the first barrel segment to the firearm;
• the distal end of the first barrel segment having a second threaded element;
• the proximal end of the second barrel segment having a third threaded element which is complementary with the second threaded element, the third threaded element for removably attaching the second barrel segment to the first barrel segment;
• a plurality of sensors comprising one or more sensors disposed on the first barrel segment and one or more sensors disposed on the second barrel segment;
• a processor operatively connected to the plurality of sensors by a plurality of conductive elements, wherein the processor is disposed on the first barrel segment;
• and
• a barrel nut assembly for removably attaching the proximal end of the first barrel segment to a receiver of firearm, the barrel nut defining an interface between the processor and further processing electronics disposed on the firearm.
