With the three position safety (metal) I notice the lever moves freely to the left and right when installed, a quiet but perceptible sound can be heard if the firearm is jostled. From a design perspective a free moving part like that seems odd to me and i wonder if maybe I did something wrong. I also noticed that when joining the upper and lower together the lever has to be moved towards the barrel or else the upper will get caught on the lower. The part seems to be functioning as intended so I really am not complaining, just curious if any others have had a similar experience. A final question I would put out.. is it okay to douse all the components in oil? Has anyone had any issues in that regard?
