Snooping around on long range shooting (competition) forums, I recently found out that Burris is no longer made in Colorado. They moved all their manufacturing overseas but they also set up all of their own machining to maintain their quality. Also, Vortex scope glass, below the razor line, is inferior to leupold VX3, while the Vortex razor binocular line has better glass than leupold binos (which are made in Asia). The pros on vortex is that the warranty and customer service are exceptional. The knocks are that the lower end scopes have inferior glass and the tracking is not consistent.
