I know of the fact that the 5.56mm has a higher pressure than the .223
I just bought.... place in layway a New S&W AR 15 Sport. It was marked to handle both the 5.56 NATO and .223 round. I even checked on the barrel and it had 5.56mm on it. But after I did a few searches online, I have read comments a AR 15 can be "marked" with 5.56mm but not be able to handle the NATO round????
Is this true... or some people who got their facts wrong?
I would think or even trust the markings on a weapon... that if it states .45ACP... I would expect to use it rather than Colt or another type of ammo.
Please, let me know... I have also picked up 420 rounds of 5.56mm... I don't want to be surpised with my fingers flying off or something.
