Firearm pin component

Image Number 4 for United States Patent #7937876.

A take down front pin and take down rear pin designed to simplify the process whereby an upper receiver is engaged with and disengaged from a lower receiver of a firearm. Each of the take down front and rear pins comprises a body having attached to a proximal end thereof a positioning member, wherein, when the pins are properly positioned to engage the upper receiver to the lower receiver, the positioning member protrudes from a main frame of the lower receiver. Furthermore, in addition to the positioning of the positioning member on the firearm such that it protrudes from the lower receiver, thereby making the respective pin easily accessible, the positioning member is also configured to facilitate the manual sliding of the pin to, within, from, and without engaging elements located on the upper and lower receiver of the firearm.
