Described
Arguably one of the most common types of ammunition used in the modern world, the .223 rifle round is a very effective high-velocity, low-weight round. Introduced in 1950 by Remington Arms as a varmint cartridge, the round was adopted by the Armalite Corporation as the ammunition of choice for the M-16, a bold move away from the high-caliber military firearms of the day.

The .223, more commonly referred to by its military metric label of 5.56mm, has found use in battle rifles, hunting rifles, and squad automatic weapons since 1957.
