Shop a wide selection of 5.56 NATO or .223 Remington barrels from quality manufacturers. Since this question always comes up, let us get it addressed up front. The 5.56x45 NATO barrel chamber will handle higher pressure than your .223 Remington barrel chamber, which means you are able to shoot .223 Remington ammunition out of a 5.56 NATO barrel. The inverse is not true, if you have a .223 Remington barrel, the chamber is not designed to handle the higher chamber pressure of the 5.56 NATO ammunition and can result in a potentially catastrophic failure, so be sure to keep that in mind when purchasing a barrel.
