I believe LOW builds to the specs provided by the company they are building for.
....there would be a lot wrapped up in that. Quality of parts used, what parts are made of, tube thickness, coatings, etc. Building exactly the same scope, but with one having a "cheaper" sourced washer, spring, etc...will result in a different quality end product. A difference that may not show up until a point in the future when that lower quality part fails.
