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?
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.
