Purpose: Pivot pins on a rifle, typically found on AR-style platforms, serve as the hinge points that connect the upper and lower receivers, allowing the rifle to be opened for maintenance, cleaning, or assembly. These pins enable the upper receiver to pivot away from the lower receiver while remaining attached, providing easy access to internal components like the bolt carrier group and trigger assembly. They are designed for quick removal or installation, often without tools, to facilitate field-stripping and ensure the rifle can be maintained efficiently.
