GEISSELE AR15/M4 Trigger Fitting Pin

The Geissele Automatics Trigger Fitting Pin is designed to assist with trigger installations. The Fitting Pin is the same size as the trigger and hammer pins, allowing the Fitting Pin to help remove an existing trigger by being able to better press the pins out, or to act like a slave pin when installing a new trigger. Compatibility: Compatible only with AR-15/AR-10 USGI .154” diameter trigger and hammer pins Not compatible with HAENEL or HECKLER & KOCH models MADE IN THE USA
