5.56 NATO vs .223 REM ... There is an Important Difference

Absolutely the best advice concerning 5.56 NATO vs .223 REM.

Ammunition - .223 Remington and 5.56 NATO... There's an Important Difference
There are differences in the chambers of specific weapons which accommodate the differences in the cartridges.

For instance, a rifle chambered for 5.56 NATO will work well with either the .223 or the 5.56.

However, a rifle chambered for .223 will only work safely with .223 since the chamber is ‘smaller'
and, therefore, can create dangerously high pressures with the higher pressured 5.56 NATO cartridge.
