No. Cases are slightly different. You can fire 223 in 5.56, but, you should not fire 5.56 in a .223

What is the difference between 223 ammo and 556MM ammo?
While they are similar, the cartridges are not the same, with slight differences in the shoulder angle, length of neck. It is safe to fire .223 in a weapon chambered for 5.56, but 5.56 ammo in a weapon chambered for .223 may NOT be safe.
Is 223 Remington the same as 556mm?
yes, except 556 is written as 5.56 caliber (223) Actually, no, it isn't. Although the dimensions match, the military 5.56 cartridge differs from the civilian .223 in several aspects, such as the neck angle, casing thickness, and chamber pressure. A general rule of thumb is that .223 Remington can be fired in a 5.56 chamber, but 5.56 ammo should not be fired in a dedicated .223 chamber.
