I've been offered an AK for sale.  The barrel is stamped AUSA.  It doesn't say if it is a 5.56 barrel or a .223 barrel.  Does anyone have any idea what type of barrel it might have?

Any help would be much appreciated as I have to let the man know about if I'll buy it or not...but don't want to if it is a .223 barrel.

5.56 x 39 or 5.56 x 45 ? i may be incorrect. Someone will be here to help you out...

Edit:  I'm stupid... I was thinking of the 5.45 x39.5 or the 5.45 x.45 rifles . sorry
