Michael, yes this is .223 Wylde, Bud's should reflect that in the description.
Stay safe & have a great day!

Hi Michael and welcome. Yes Sir. The Wylde is a compromise between a .223 chamber and 5.56 chamber to lessen the accuracy gap from firing .223 from a 5.56 chamber. In short, it is an in between chamber length of a.223 and 5.56 chamber length. 5.56 or .223 can be fired no issue. Cheers and stay safe!

Michael, yes sir, this is 223 Wylde so you can safely fire 223 and 5.56 through it. Hope this helps.
