    When the US Army had the need for a low caliber, high-velocity cartridge, the .223 Remington cartridge was born. While its origins can be traced back to 1957, 223 Rem remains one of the most popular rifle rounds due to its versatility and lower price per round compared to other calibers. Whether you need FMJ bullets for training or hollow points for defense, OpticsPlanet carries all the cartridges you need. Browse our entire selection of ammunition to find AR15 ammo, shotgun shells, and tons of other rounds for your favorite firearms.

    223 vs. 556 Ammo

    Before you buy, it’s important to understand that .223 Rem and 5.56 NATO are two different cartridges. For an in-depth breakdown, read our guide on The Differences Between 223 Remington & 556 NATO Ammo. In short, both rounds have the same dimensions in terms of bullet diameter and case length. The main difference is that 5.56x45 ammo has a higher chamber pressure, which results in less bullet drop at longer distances, improving long-range accuracy. It is important to know that you should never fire a 5.56 round through a rifle chambered in .223 Remington. However, it is safe to fire a .223 rounds out of a 5.56 rifle.

    What Is the .223 Round Good For?

    .223 Rem rounds are versatile and excel in multiple areas. Due to its low cost per round, 223 ammo is the perfect plinking cartridge, especially for high-volume shooters. Don’t let the lower price fool you, 223 ammo is incredibly accurate, has a flat trajectory, and produces low recoil, making it an ideal choice for long-range competitive shooting and 3-gun matches. It is also widely used to hunt varmint and predators like coyote. 223 Remington is as close as you can get to an all-around amazing cartridge.

    How Do I Know if My AR Is 556 or 223?

    The caliber is usually stamped on the barrel or receiver of your AR-15. If you are having difficulty locating that information, you should reach out to the manufacturer or whoever you purchased the firearm from.
