Colt HBar question

[Weare138]

I inherited my dads Colt HBar and I have what may sound like a rookie question. The lower says Colt Match Target Competition HBar and caliber .223 however the upper says its a 5.56 NATO 1/9 HBar on the barrel. Would it be safe to shoot 5.56 since the upper is stating 5.56?

Thanks

I am no expert but my understanding is that match colt rifles were chamberd in 223..unless other wise. I sure some colt experts will clear up your questions.

Same here. Thought they were/are .223 but when I took it out for a cleaning and lube tonight I saw the marking on the barrel that made me go huh?!?

Guys, think about this. Where does the round go BANG?! In the barrel or in the lower?
