Our .223 Remington is also labeled as 5.56×45 / 5.56 NATO as .223 Remington can be fired safely and with good results out of both chambers as well as the .223 Wylde chamber. It is advised not to fire factory 5.56 out of a .223 chamber as there is a pressure increase and chance of damage or injury can occur.
