This is one of our most popular rounds-especially among our military customers. It is used for target shooting, service and survival. It is the round used in the AR-15/M-4/M16 rifles. The .223 Remington has almost the same external dimensions as the 5.56×45mm NATO military cartridge, which is why we categorize them together. Popular firearms that use this cartridge are the AR-15 and Remington .223.
*An interesting side note here about a misconception spread by the anti-gun lobby: the “AR” in AR-15 does not stand for “Assault Rifle” – it stands for “ArmaLite,” a registered trademark for the gun.
