.223/5.56 / .223 Remington / 5.56x45mm NATO Ammunition

Although the .223 Remington and 5.56x45 NATO cartridges are quite similar, there are some differences. Enthusiasts of .223 / 5.56 pistols and rifles know well that the rounds are not fully interchangeable, unless you have a Wylde or ArmaLite chamber that can handle both. So remember, you can chamber a .223 Remington round in a 5.56 NATO gun, but you can’t do the reverse. Due to the shorter leade of the .223 rifle, the bullet comes in contact with the rifling of the barrel too soon, and the increased pressure can damage the cartridge or the gun. We carry a nice variety of .223 / 5.56 subguns and pistols from manufacturers like Zastava, FedArm, and MKE Firearms.
