I have dealt with Phil at White Falls. A great guy. I bought an 8-32 target scope with side focus. A great scope. The Tac II is nice as well. Great optics for the money. The 8-32 is easily the equal to a Nikon Target scope I have IMO. IIRC, glas is from Germany or Japan and assembly is in the states. Being in Winnipeg made it easy for me. White Falls being the Canadian distributor handles any potential Warranty issues. White Falls has a website, check it out for their contact info.
