Overview

This compact two-tool kit is designed to simplify front pivot pin work on mil-spec AR-15s, making removal and installation more manageable during armorer tasks or routine maintenance. One tool compresses the spring-loaded detent to free the pivot pin, while the other helps guide the detent and spring into place and acts as a slave pin during installation. It is intended for use on all mil-spec AR-15s except those from Colt Mfg. For hunters and shooters who maintain their own rifles, it offers a practical way to reduce frustration and keep small parts under control.
