I guess it all comes down to the reason you want to know.
Yes. And I suppose also... the reason they don't want to tell me?
I can totally understand wanting to know for political/economic reasons (i.e. is it made in a country that you don't want to support with your dollars?),
I do have a preference, but that is all it is (a preference).
but if you want to know because you think a particular country can produce a better piece of glass than another,
Not necessarily anything to do with the "Country" where it is produced, but the COMPANY who manufactures it. Since we are not privy to the 'origin' of manufacture, the next best clue...would be the company.
And YES....there are a few well respected optics manufacturers with MANY more years experience making good glass...than certain others.
I understand that 'supposedly' the glass would be produced to a certain price point (grind,polish,coatings).
Whether or not that happens with the lesser known manufacturers...I can not say, but the better Asian companies have a solid track record.
IF a manufacturer in the Philippines/Other can truly produce a product of equal quality, good for them...the market will slowly recognize and reward them for that.
Unless Vortex is afraid the origin of their glass (in the VIPER line) would be 'perceived' as a lesser quality item, then why would they not promote it?
just let your eyes make the decision - if it looks good enough to you, what difference does it make where it was made or who produced it?
It would not make a difference to me (unless Chinese made). As you allude to...the product would either satisfy me or not.
However, I do not have a source (anything like locally) where I can go and "look" through the scope. I am sure that is true for many folks.
So I am doing my best to make a decision based on information I can gather and the testimony of others (who may or may not know a good product when they see it).
While the scope is certainly not 'expensive', it will have a street price of about $600.00. Just enough that I would like not to be overly disappointed.
Again, not a problem...IF I could put my hands on one before purchasing.
Remember this famous line:
"We have to pass the bill to see what is IN the bill". ?
Analogously, I would like to avoid that kind of surprise.
(purchase one...so I can look through it)
IF I fail to do my 'homework' and purchase an optic of no outstanding value, then it will be my own fault.
But, that becomes more likely when/if the manufacturer is less than 'helpful' in providing answers to simple questions.
I am not exactly soliciting 'trade secrets' from them...you understand.
