Winchester USA ammunition (brand part no. WM8551000) delivers genuine Lake City-manufactured M855 Green Tip in 5.56mm NATO, chambered to also run in .223 Remington rifles. The M855’s signature green tip marks its steel penetrator core, a design distinct from standard 55-grain FMJ ball ammunition. This is military-grade ammunition, so cases may show discoloration from the annealing process and minor blemishes from bulk packing, both completely normal and not a defect. Winchester packages this Lake City-manufactured round in a 1000-round bulk case for shooters who train often.
