Patent attributes
A takedown pin assembly for a firearm is disclosed. The takedown pin assembly comprises an elongate pin, a spring, and a head disposed on one end of the pin. The pin further comprises a channel extending along at least a portion of the elongate pin in the direction of the pin's longitudinal axis. The channel has a width sufficient to receive a detent pin from a firearm. The elongate pin is configured to fit within a hole in an upper receiver or lower receiver of a firearm. The head has a lever handle extending laterally from a center portion of the head. A user engages the lever on the head to rotate the pin and allowing the detent pin to travel in the channel. The spring pushes the pin out from the firearm receivers to allow the user to open the action.
