Aguila M855 Green Tip 5.56mm 62gr FMJBT, 300-Round Box

Built to the same specification fielded by U.S. and allied militaries, Aguila M855 Green Tip 5.56mm ammunition (brand part no. 1E556125) fires a 62-grain FMJBT bullet with a steel-core penetrator. Aguila Ammunition manufactures this load to full M855 specification, giving the boat-tail bullet a flatter trajectory and better long-range consistency than standard 55-grain 5.56 ball ammunition. The green tip marks a steel penetrator seated ahead of the lead core, adding hard-target capability that soft-core FMJ rounds do not offer. Whether stocking up for training, competition, or a duty rifle, this 300-round pack of M855 rifle ammunition covers a serious volume of trigger time.
