The bolt has the standard oval gas escape holes, therefore came from a factory making military actions. The receiver serial number is in the right place for a Zastava sporter made for Herters. The stamp on the left receiver ring does not show up clearly but is most likely ZCZ inside a circle, for Zavodi Crvena Zastava. The safety button appears different from what I recall but that may not be significant. Zastava rifles and actions have been imported to the U.S.A. by Herters and Interarms.
The rifle looks nice and so long as it is safe and puts the bullets where you want them you probably know all that you need to know about this rifle.
Have fun shooting it.
