The AR-15 pivot pin detent spring, as are all of our Keepshooting.com house brand spare and replacement parts for the AR-15 platform, is a brand new part produced in a state-of-the-art manufacturing facility that holds several foreign military contracts. As such, all parts are compatible with and interchangeable in any MIL-SPEC AR-15.

Located in the small, recessed hole at the front of the lower receiver adjacent the pivot pin retaining ears, the AR-15 pivot pin detent spring is a small spring designed to hold the pivot pin detent in place and under tension. Together, the aforementioned components serve to hold the pivot pin in place. With enough force, the pivot pin is capable of being dislodged so that the rifle may be disassembled.  

Spare and replacement parts are an important consideration when it comes to firearms. Like any machine, firearms rely on a series of parts to function properly – especially those components that may have an impact on the firing sequence. In general, if a part breaks or fails, a repair or replacement becomes immediately necessary – not only to keep a firearm functioning properly but also to ensure the safety of yourself and those around you.
