Ok received it and looked at my unfired 30" .223 barrel. All I can say is wow. How this barrel looks is terrible. I compared it to a new browning barrel. Now I know why there are so many aftermarket savage barrels. I did not take pics yet. I'm gonna slug it and see how that goes. So I will shoot it for a while to see what happens. If it's bad I will fire lap it. That don't work it's a fire poker. Should have just built the rifle. Lesson learned. Maybe I'll shoot it and it will be a tack driver, you never know. I give kudos to the boroscope. I never knew the inside of my nose looked like that. Seriously, for the money, it's a great deal. Glad I got it. All the barrels I've looked at 8 or 9 now, new and old, mossberg to rem, win, browning, sfa, the savage barrel is by far the ugly duckling. Wow, I mean by a lot. I see new barrel in my future. We'll see.
