I recently purchased a Colt AR-15 heavy barrel match target rifle. Although the receiver is marked .223, the barrel says 5.56 Nato, Heavy Barrel match Target.
I don't like to mix 5.56 in a .223 rifle. Do I follow the receiver imprint or the barrel imprint? Can I use both in this rifle? Any input is appreciated.
