AR-15 Windham Weaponry Government 20" and the Sightron STAC 10Oct2021

Published on Oct 10, 2021
Sighting in the Windham Government 20" iron sights today at the standard military 25 meters and got very close to where I wanted to be with a 50 yard zero using the Sightron STAC before I ran out of ammunition. I was using some 55 grain 223 factory reloaded with different head stamps and new Winchester 55 grain 556 NATO for the final zero. NATO definitely had more pop!
