I carefully smoothed out the ragged crown and the accuracy improved greatly. It is very acceptable accuracy for the price.

Spot on analysis. My experience and observations (barrel crown, accuracy, etc.) have been exactly the same. Although the groups were "acceptable", they were nowhere near the accuracy of my Glocks.
Here was a 12 yard/36 foot group shot standing unsupported onto a 7" paper plate. While it may look acceptable, my Glocks will clover leaf everytime with no crazy flyers that come out of nowhere.
While I have not messed with the crown, I did pick up a factory threaded barrel, so we'll see if there is any difference this weekend. Out of curiosity what did you do to smooth out the crown chatter?
