Just discover my barrel locking screw not completely "locking" down the barrel as I was extending the shroud on my Impact by just twisting the telescopic shroud. The barrel locking screw was tighten down when this happen. I verify this with the .22 .25 and .30 barrel and all three barrels are doing the same thing. I remove the screw completely to confirm that the barrel was aligned. When the screw is tighten down the barrel has less movement then when without the screw in place. I have a video which show the small movement on the barrel. The post it paper attached to the barrel is just for visual purpose on the video. I don't know how will this affect the transfer port alignment or POI. Looks to me that the locking screw should be a little longer and more rounded at the tip. Anyone else have this happen with their Impact?
