"The serial number really is in a bad place. Since the pistol is designed for the US market and most buyers will probably SBR it they really should have picked a different location"
Well... covering it up with a stock mount does not remove or deface it... it just hides it. Really, I don't see this as a show stopper. Plus when you Form 1 a SBR as the manufacturer, don't you assign it a new number and need to engrave the name of the "new manufacturer" on it anyhow? Most people re-use the old number, but... add that same old number elsewhere and leave the hidden one in place so it's not "defaced".
Good review, I'll score one as soon as I can.
Zastava, BTW, made the entire line of "Mark X Mausers" that were imported by Interarms for years. Definately a high quality builder.
