On one level, Gun Test is quite right to go thumbs up or thumbs down on what comes rat out of the box, because that's what happens to real buyers.
But by the same rigid standard, I'd have to tell other shooters that all Marlins, Rugers, Colts , and Sigs are pieces of clinton, because I have had models from each fail right out of box.
There are some basic realties of the gun business. With the exception of certain "lexus" models, there is fierce price competition, meaning that some final testing/evaluation gets cut short.
This means that some pieces come out needing some extra work. That's reality. The good news it that most problems can be easily fixed.
