The point I'm trying to make is just because the first scope you pick is a dud doesn't mean you can infer that that scope and/or scope manufacturer is going to have a higher failure rate on their scopes than a manufacturer that did not yield a dud on the first scope you grab. As you note, they are all random picks, and as such each scope, dud or not, has an equal chance of being selected. If you get a dud on the first pick, it is more than likely bad luck rather than the manufacturer's bad product. Now, if a lot of people are getting duds (which according to folks who are running the Tract Optics, is not the case) on the first random selection then you have an argument for poor manufacturing/quality and poor QC.
