Savbage_99: I am happy you are happy with YOUR 358!
The OP Rifle is definitely bogus.
And for your information the "0" as you reference, on fakes is first "filled in" and then restamped "to a 5" in case you have never seen one of these attempts at fakery.
On the several fakes I have seen in person over the last several decades (and ones as recent as last year here at gunshows in SE Idaho and central Montana) they have ALL been filled in, then stamped over - there is no evidence on any I have seen of the "0" like you allude to being visible at all.
These "faked" 358's are still easily discernible both by the obviousness of the "restamp" but other obvious clues like being out of serial number range for an original 358, incorrect stock style etc etc etc.
Sad that anyone would try to make a buck by deceit/forgery.
The 358's I have bought and own were inspected with high powered optical devices EXTREMELY carefully/closely - only then did I move forward to check out the Rifles other defining attributes.
Buyer beware - be VERY aware.
Hold into the wind
