AR-15 Pivot Pin

Features

1. 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.
2. Steel Construction — Solid steel build delivers the strength and wear resistance required for repeated takedown and reassembly cycles.
3. Phosphate Finish — Matte black phosphate coating resists corrosion and matches the factory look of mil-spec AR-15 small parts.
4. Front Receiver Pin — Installs at the front pin location to allow the upper receiver to pivot open from the lower for cleaning and inspection.
5. 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.
6. Direct Replacement — Drops in to replace lost, damaged, or worn pivot pins on AR-15, M4, and M16 pattern rifles and pistols.
7. Builder-Friendly — A must-have component for any AR-15 lower parts kit, spare parts box, or ground-up build.
8. Compact and Lightweight — Adds no meaningful weight to the rifle while performing one of the most critical hinge functions on the platform.
