I personally wouldn’t have any hesitation with putting either the V4 or the VX-5 on a 30-06 for the hunting applications you’ve described. Don’t have any direct experience with Trijicon so really cannot comment there. Currently running VX6HDs on my main hunting rigs - relatively light, rugged, and so far no tracking or other issues. So far they appear very well made and durable. But as with any complex device with moving parts someone will always be able to point to a failure with some individual samples. Used to use Swarovski, love their designs but have experienced both internal fogging and loss of zero and no longer trust their durability.
Would recommend dismissing all inferences drawn about place of manufacture. Noticed a significant uptick in the number and frequency of place/source of manufacturer claims both here and all over the internet over the past few years. Although rarely confirmed or examined in-depth, these claims are often stated and repeated with deep conviction, and all manner of inferences about product performance and quality drawn from them. However, many, if not most, are over-simplified, inaccurate or exaggerated. Fact is most complex optical devices involve materials, components, sub-assemblies, etc, from multiple sources. For example, many optics manufactures tout “Schott Glass“ and heavily market that in their product advertising. However, Schott began manufacturing optical glass outside Germany as early as 1967. Today, Schott glass is made in over 30 countries, and when glass is ordered Schott will source it based on the specified grade and performance characteristics. But the highly touted “Schott HT” glass used in someone’s favorite binocular or scope could just as easily be coming from a Schott plant in China or Indonesia as from Germany or Austria. But that glass is made to the same Schott-controlled manufacturing process and performance specifications regardless of where it is coming from. Also, folks love to throw around OEM names like LOW & Kamakura. But it is naive to think those OEM manufacturers are not also using worldwide sourcing. That‘s just reality in today’s global economy.
Point is - we would all be better served by drawing conclusions via actual direct comparison and field performance rather than speculation about where they are made.
