I recently ordered a 223AI barrel from Jim at Apache and figured I would post the results. I made my first trip to the range the other day, and I couldn't have been any happier! All groups were under 3/4'' at 100 yards with many of them under a half inch, with the smallest being .265'' (with zero load development!). Jim was quick answering my emails, was knowledgeable, and got me my barrel quickly and for a good price. Thanks!
