Ed:
States plainly on their website under the Q&A section of the Razor HD spotter (20-60-80) straight, that it's made in China, a question posed by a customer and answered by a company (Vortex) rep.
I have two viper PST's and it states on the erector, on the bottom of each, 'Made in the Philippines, I've had them for a couple years now so that might have changed, not sure. I am sure I prefer the Philippines over China though.
I just (this summer) bought a Diamondback 4-16 side focus 1" tube for my Husky. I also states 'Made in the Philippines and on the Vortex site, again under Diamondback in the Q&A section, a customer asked where it was made and a company rep answered... Philippines....
Interesting that the Razor is made in China versus the Philippines for the rifle scopes.... I wonder if the Razor Riflescope is Chinese too???
I'd say like Leupold, glass comes from the lowest bidder so long as it meets the minimum requirements of Vortex.
