I meant 5.56.There's no sucj thing as .556 ammo or guns.Are you aware that they sell .556 ARs to civilians?And anyone that knows the difference between the .223 and .556 knows that the .556 is hotter than the .223. You should not fire the .556 in civilian guns for any reason. The chamber pressure of the .556 exceeds the safe limits of the civilian gun. The same goes for the .308 and the 7.62. And God Forbid if you take 7.62 ammo off the belt of a M-60. While the round fits in your .308, the pressures sooner or later will blow your chamber out. Military Rounds are hotter and some are even hotter like the M-60 7.62 round or the belt fed .556 ammo.
