Strike Industries has released a novel contraption: the AR Trigger Hammer Jig for AR-series weapons. As Strike describes the jig:

The AR15 Trigger Jig allows you to clearly see the sear, hammer, and disconnector engagement points while under normal spring tension. The Trigger Jig enables you to dry fire the trigger without damaging the jig or other internal parts and make necessary adjustments while checking functionality.

If one mounts it in a vice, you can measure trigger pull. The jig package includes the pins, hammer block, grip adapter screws, and grip adapter. It is available for $39.95 on Strike Industries’ website.
