    I read alot about mechanical accuracy etc.

    What kind of degradation in performance are we talking about here after 10k rounds?

    By "ruined" do you mean the barrel becomes dangerous to shoot or what? Obviously a barrel isnt going to become inoperable at exactly 10k rounds.

    Ive read that its a good idea to replace gas tubes every year or so just to guarantee that nothing goes boom where it shouldnt.

    In the test article I referred to above, the barrel was keyholing rounds when they fired it on paper. That's a ruined barrel.

    Also, I have an AR uppers that is over 10 years old with 7 to 10 thousand on it (as mentioned above). I've never changed a gas tube on it or any other upper I own for that matter.

    S.A.W told me they can be changed every 3 thousand rounds, but their advice was so strange on the other two issues I asked about that I didn't put much stock in that opinion.

    Demigod, sorry for the "noob" question but what does keyholing mean?

    an oblong hole in the target...which shows that the round is tumbling and not stabilizing.

    Yep. The bullet is not spinning like a football. It's tumbling end over end. That can have an impact on the accuracy of the weapon.
