Winchester Modest Rifle Primers forty one
Winchester NATO-Spec Navy Primers forty one are precisely the same primers used in the Lake City 5.56mm ammunition. These primers are crafted to exacting specifications for shot to shot consistency. All primers are regularly winchester 41 primers and rigorously analyzed for regularity and sensitivity at temperatures and situations significantly further than the selection of usual use. Winchester assures cautiously-controlled weights of primer mixtures, consistency in dimension and good quality, exact measurements and tolerances for anvil heights and security in extremes of temperatures and humidity.
