Sorry but this is utter BS, bordering on trolling. Are you one of those intellectually lazy types who had a problem with one rifle and used that as an excuse to condemn 53yrs of Ruger rifles? If what you said was actually true, then it would be the only junk rifle that thousands of people use as the basis for a custom rifle.
They function just fine out of the box. People spend money on them to make them
better. The fact that they do does not imply that there's anything wrong with them out of the box. It implies that the 10/22 is a better basis for modification than any other semi-auto. For one can spend a little money and have a semi-auto that shoots better than your precious CZ. Mine does, circles, in fact.
