AR-15 Pivot Pin
The United Defense AR-15 Pivot Pin is a mil-spec front receiver pin that hinges your AR-15 upper to the lower for fast takedown and reassembly. Machined from steel and finished in phosphate, it meets standard AR-15/M4/M16 dimensions for a true drop-in fit on any mil-spec lower. The detent groove keeps the pin securely retained during use, while the matte finish blends with factory small parts. A smart pickup for builders stocking a lower parts kit or any shooter who needs a reliable replacement for a lost or worn pivot pin.

Features
- Mil-Spec Dimensions — Machined to standard AR-15 specifications with a ~0.247" pin diameter for a drop-in fit on any mil-spec lower receiver.
- Steel Construction — Solid steel build delivers the strength and wear resistance required for repeated takedown and reassembly cycles.
- Phosphate Finish — Matte black phosphate coating resists corrosion and matches the factory look of mil-spec AR-15 small parts.
- Front Receiver Pin — Installs at the front pin location to allow the upper receiver to pivot open from the lower for cleaning and inspection.
- Detent Groove — Cut with the standard retention groove so the pivot pin detent and spring lock the pin in place without walking loose during use.

- Builder-Friendly — A must-have component for any AR-15 lower parts kit, spare parts box, or ground-up build.
