AR-15 Takedown Pin
The United Defense AR-15 Takedown Pin is a mil-spec replacement rear pin for the AR-15, M4, and M16 platform. Machined from hardened steel and finished in black phosphate, it drops into any standard mil-spec lower receiver and pairs with a factory detent and spring for secure retention. The .248" diameter and standard groove geometry mean no fitting or modification is required. A smart pickup for builders completing a lower parts kit or shooters replacing a worn, damaged, or missing takedown pin.

Takedown PinI needed to replace an old pin on my rifle that had worn out over time. This new pin arrived brand new and ready to use. It locks into place firmly so the rifle stays secure when I shoot it. I also bought an extra one to keep in my range bag for emergencies. It is a small part but very important for safety. I feel confident knowing the pin is high quality and will not fail. It is a simple fix that makes a big difference.
