Money well spent! I got it back a couple of weeks ago but hadn't had time to check it out until today. I didn't have much time today, but I put 3 mags of JSB Kings through it over the Chrony before I decided I was just wasting air as the range was 853 fps to 855 fps for all 36 shots with a bunch of dupes at 854. I mounted the scope and zero'd it at 30 yards, then put 3 mags through the same hole. I can't wait to stretch it out to 100 and see how she does further out. It was capable of sub MOA groups at 100 before I sent it out and the post tune velocity is up about 30 fps and is far more consistent than it was prior. I also had Martin add an accessory rail to the front of the stock while he had it. That came back perfect as well. I think it looks pretty damn good too!
