Winchester Compact Rifle Primers forty one

Winchester NATO-Spec Armed forces Primers forty one are the exact same primers used in the Lake City 5.56mm ammunition. These primers are built to exacting specs for shot to shot consistency. All primers are frequently and rigorously tested winchester 41 primers for consistency and sensitivity at temperatures and problems significantly beyond the array of usual use. Winchester assures carefully-controlled weights of primer mixtures, consistency in size and top quality, precise measurements and tolerances for anvil heights and balance in extremes of temperatures and humidity.
