There are previous threads on this subject and several folks have this problem. These guns are very accurate, but the POI does move around from time to time reported by several people. I believed that the issue was the fact that the barrel & shroud is only supported at the receiver and the if the fit is not spot on perfect ,it shifts after being knocked about even a little bit. On my gun it is always a little different at every session. Well, I ordered a bottle to shroud brace made by 3D printer from Ohio Airguns. The fit was phenomenal, just perfect.. I have now tested this over many sessions and the problem no longer persists. I can handle the rifle by the barrel and transport it and the POI now remains the same. Best $20 I ever spent.
