Strike Industries SI-AR-THJ AR Trigger Hammer Jig for Trigger Setup

Overview

This easy-to-use apparatus lets you fully assemble and test any AR-15 trigger setup before installing it in a rifle. The jig holds parts under normal spring tension so you can clearly observe sear, hammer, and disconnector engagement, dry fire safely, and make adjustments on the bench without risking scratches to your lower.

Mount it in a vise to measure and adjust pull weight and demonstrate function.
