How would you actually know what a good rifle is? Your criteria for quality checking is inly to move the bolt back and forth a few times?
I took one of your favorites, a Brno blued rifle on a coastal grizzly hunt. Even though prior to the hunt I treated it with rust preventative, every day I was removing rust from the rifle with an oily rag. In contrast, I own a stainless/synthetic Ruger that was stolen in July and left out all winter in the rain and snow until the next May when it was found- and after rinsing the mud off it, it was ready for action- no rust. If it was a Husqvarna it would have been covered in rust and the stock need refinishing at minimum.
Some of us are more concerned about reliability in hostile conditions than how pretty our tools look.
I realize that you don't hunt in rugged mountains or near salt water or in rain forests, but some of us do.
