This is M855 ammunition (or SS109, if you’re not an American). Each round of 5.56 has a 62 grain bullet, which is a little heavier and will fly most accurately after it has exited a barrel with a 1:9 or 1:8 twist (but 1:7 works good enough as well). On the exterior the M855 bullet is functionally identical to an FMJ: a gilding metal jacket that ends in a pointed tip.
That pointed tip is painted green to indicate what’s special about the M855 bullet. The front of this bullet’s lead core contains a steel “penetrator” tip, which helps it defeat sheet metal and other types of barriers. This is why M855 ammo is used by the Army against vehicles and lightly armored targets!
Armscor makes consistent ammo. The ISO 9001 certified Philippine manufacturer gives their ammo responsive Boxer primers, evenly loaded propellant, and reloadable pure brass cases. This ammo’s bullets are magnetic, though, which limites the number of ranges you’re allowed to fire them at.
