I had GAP turn one for my AIAW in 65 creed and it shoots under 1/2 MOA with factory Ammunition consistently. This is my second barrel and I had the exact same results with the first one.
The F..ked up thing is that they have come to expect it. Since I work rural ER medicine I run into this quite a lot, what's churns my nut sack is that I have to pay full price for my childrens health care and these curb worms get it for free.
