The 5.56mm M855 has a green bullet tip and is used by the U.S. military as its standard small arms round.
Adopted by NATO in 1980, the new load has a spitzer boat-tail bullet. It also has much-improved penetration characteristics over the old M193 55-grain projectile at all ranges, resulting in higher retained velocity and greater accuracy at long range. The 5.56mm M855 is ideal for use in the M16A2 and M4 rifles, and the M249 machine gun.
