Patent ID: 8458948

Claim:
A method of refurbishing a rifle comprising the step: delivering an apparatus comprising a mounting bracket, at least two 6-axis robotic arms, a ultrasonic cleaning tub, and a coordinate measuring device to a location; providing power to the apparatus; mounting the rifle on the mounting bracket; gripping the upper assembly of the rifle at its barrel with a first robotic arm; pressing out the upper assembly upper release pin via a second robotic arm; using the first robotic arm to pivot the upper assembly downward while the second robotic arm presses out the upper assembly lower release pin; using the first robotic arm to separate the upper assembly of the rifle from the lower assembly; holding the upper assembly with the first robotic arm and using the second robotic arm to remove the charging handle and bolt carrier group from the upper assembly; placing the upper assembly, lower assembly, charging handle, and bolt carrier group into the cleaning tank via the first and second robotic arms; using the first robotic arm to deliver the upper assembly to the coordinate measuring machine and using the machine to check the specifications and tolerances of the upper assembly; using the second robotic arm to deliver the lower assembly to the coordinate measuring machine and using the machine to check the specifications and tolerances of the lower assembly; installing the charging handle plus bolt carrier group on the upper assembly via the robotic arms, if the upper and lower assemblies' specifications and tolerances are compliant; using the second robotic arm to return the lower assembly to the mounting bracket and engaging it with the clip port; using the first robotic arm to reunite the upper assembly with the lower assembly; and, removing the rifle from the mounting bracket.
