Hi I just replaced the rollers in my cetme with some +4 rollers from RTG. Before installing them I had zero bolt gap and less then a dime of cocking tube gap. After installing them I have zero bolt gap and my cocking tube gap is now zero as well. As soon as there is any resistance at all I can seem the cocking tube support touching the bolt carrier. Does anyone have any advice or know of a good gunsmith in Louisiana that deals with cetmes. Well thanks for your time.
