So I purchased one of these. I disassembled the rifle for cleaning. The barrel inside is very shiny. After I put it back together, I cycled 12 unfired rounds through it to test feeding and it performed flawlessly. I even cycled them very fast with no hang ups. I haven’t shot it yet, so accuracy is still to be determined, but so far so good. I’m very happy with this $400 purchase. I will report back on Monday after I shoot it. Fingers crossed that it will be accurate. If it is then there is no more I could ask from it.
