Geissele Automatics AR-15 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 act as either a punch to help remove an existing trigger, or to act as a slave pin when installing a new trigger.

An inexpensive, and essential tool to save time on any new build or retrofit.
