Skeletonized aluminum jig allows you to observe the function of the sear, hammer, and disconnector engagement points under normal spring tension. The jig interior is machined to the exact dimensions of the AR-15 fire control pocket. Open sides provide ample access to adjust the trigger assembly without removing it from the rifle. The jig can be mounted in a vise or on a pistol grip. A plastic block enables dry firing without damaging the hammer or jig.
