.223 vs. 5.56: Ammunition Comparison and Overview

Using commercial .223 cartridges in a 5.56-chambered rifle should work reliably, but generally will not be as accurate as when fired from a .223-chambered gun due to the excessive leade. There always seems to be a lot of confusion over the difference between a .223 and a 5.56 chamber. I often receive questions asking if someone can shove 5.56 ammo into their new AR-15. The quick answer is maybe. Just because a gun has .223/5.56 scribed on the barrel, does not mean it can handle either piece of ammunition equally.

Some are genuine manufacturers and others are small operators putting together rifles from outsourced parts. As long as the parts are high quality, that is fine. There is a lot of talent in the business. Diamondback’s DB15 exemplifies such talent.
