Jaywalker,
I put more than 6000 rounds down my 19.5 inch barrel before I sent the upper back for rebarreling. I shot lots of .25 inch 5 shot groups at 100 yards, and plenty of sub 1/2 MOA groups at 200 and beyond. Even at 600 rounds it would still shoot sub MOA with a couple loads, though it wasn't as accurate as it had once been.
I field tested for Bill Alexander, so I am harder on parts than most. I managed to break one experimental bolt in that time. I didn't break ANYTHING else. I ran factory AA, factory Black Hills (both the 123 grain SMK load of 6.5 Grendel and the 123 grain Hornady load), and lots of different hand loads, including some that were very warm.
The only thing I replaced was the experimental bolt, which broke after about 3000 rounds.
I didn't manage to break anything else.
Hope that helps!

You seek escape from pain. We seek the achievement of happiness. You exist for the sake of avoiding punishment. We exist for the sake of earning rewards. Threats will not make us function; fear is not our incentive. It is not death that we wish to avoid, but life that we wish to live. - John Galt
