Winchester M855 .5.56 NATO Ammunition 20 Rounds FMJ 62 Grains SS109 Green Tip Loaded in Lake City Brass USA855K

Winchester SS109 Green Tip Penetrator

Loaded by Winchester using Lake City Brass and packed in the Winchester white box, this M855, SS109 ammunition features a 62 grain full metal jacket bullet with a lead alloy and steel core. These green tip rounds are designed for use with the AR platform. The denser materials give the round the added weight that it needs. The added weight can also come in the form of a thicker brass jacket. When a full metal jacket exceeds 25% of the projectile, it becomes an armor-piercing round.

20 Rounds per Box
