Winchester Compact Rifle Primers forty one
Winchester NATO-Spec Armed forces Primers forty one are precisely the same primers used in the Lake Metropolis five.56mm ammunition. These primers are built to exacting specs for shot to shot regularity. All primers are frequently and rigorously winchester 41 primers tested for consistency and sensitivity at temperatures and situations significantly further than 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.
