Barrel is great. Exactly what I ordered. Shipping was quick. My only issue is that the barrel came in a corrosion resistant bag that someone had opened prior to shipping, which led to the barrel having corrosion on it. I was able to clean most of it up but there still some in the bore that I can’t get to. That’s why I give it 3 stars. Barrel great. Opened corrosion resistant bag not so great
