Winchester #41 Small Rifle Military Primers
The primers used in Lake City 5.56mm ammunition are Winchester NATO-Spec Military Primers. For uniformity from shot to shot, these primers are constructed to stringent standards. All primers are extensively and continuously tested for consistency and sensitivity under situations and at temperatures well outside their typical operating range. Winchester ensures exact measurements and tolerances for anvil heights, uniformity in size and quality, and stability in the face of fluctuations in temperature and humidity.
