what are the chances that this barrel is OK for 556 ammo? i am having no luck finding any markings on the barrel.

From what I can see all 556/223 barrels are good with 556, even the .223 Wylde.

Correct223 barrels ARE NOT good with 5.56.
5.56 barrels ARE good with .223
Correct
Seeing as all the barrels in that link are clearly marked "5.56", I'm not sure where that comment came from.
We still have no clue what barrel the OP was asking about. For all we know, he could be laid up in a snow bank somewhere, with the engine still running...
PopPop. From your last post, it looks like you suspect "HBAR" is a specific ammo-type barrel. It is not. HBAR only represents that it has a "heavy barrel" contour, which is the only legal purchase currently in Maryland for a complete AR built or sold/traded after 2013.
- A 5.56-marked barrel (HBAR or otherwise): Can accept 5.56 and .223 ammunition, as other ops explained. It fires 5.56 moreaccuratelysafely than it fires .223 (ops, please correct me if I'm wrong)
- A 223-marked barrel (HBAR or otherwise): Can accept ONLY .223 ammunition pressures; it CANNOT safely fire 5.56 ammo. It fires .223accuratelyonly.
- A Wylde-marked barrel (HBAR or otherwise): Can fire 5.56 and .223 ammunitionwith similar/equal accuracysafely.It fires .223 more accurately than a 5.56-marked barrel can fire .223 (again, ops please correct me if I'm wrong). And it fires .223 equally well. However, it will not fire .223 as well as a .223-marked OR 5.56 as well as a 5.56-marked barrel will.All depends on the barrel.
So, we'd need to know more about your AR upper. Or, did you buy it as a complete Anderson AR, built by the Anderson manufacturer and not built by some random guy like me? If so, Anderson can probably help. Does the lower receiver have a model number marked on it?
Thanks for the update!For anyone still interested I finally found the barrel marking. After shining a flashlight through the hand guard holes numerous times and not seeing any markings I removed it. The barrel marking was underneath the gas tube. It was marked 5.56 NATO. So I'm happy I can use both 223 and 5.56. Thanks for all the responses!

That's good news but keep in mind that you should have headspace checked to confirm.
