.223 Remington, or 5.56 NATO, (commonly pronounced two-two-three or two-twenty-three) is a common rifle cartridge that was borne from military applications. Designed to fit the action length of the M16 service rifle, it quickly gained civilian popularity due to the wide availability of brass for reloading. Once the AR-15 became available, the .223 became even more popular. Due to the popularity of the .223/5.56 NATO, ammunition has become equally popular and varied. Many manufacturers have developed very specialized rounds, each catered to the application. Some of the biggest innovations have come in the home defense and hunting applications, developing frangible, fragmentation rounds that transmit maximum damage on soft tissues, but fragment on contact with hard surfaces.

Clark Armory carries a wide assortment of .223 ammo, from frangible rounds to solid copper high-penetration rounds. Whether you are looking for a hunting or home defense application, Clark Armory has everything you are looking for.


The flexibility of 223 ammunition is another one of its many outstanding features. It is compatible with many different rifles and can be used for defensive purposes, target practice, and even hunting. In addition to being a popular option among regular shooters and novices who don't want to spend a fortune on ammo .22 caliber ammunition is readily available and inexpensive in comparison to other calibers. The 223 ammunition is well-liked for its low recoil in addition to its accuracy and adaptability. This facilitates precise shooting even for novices or those with smaller hands. Rapid fire may be required in some scenarios, and the minimal recoil makes this a useful option to have.
