Im not saying you do. But when I was a rangemaster I would see FNGs with their M1icon Carbines they got from Granpa, or Uncle George that passed, or the local gunshow. They had the habit of trying to close the bolt by hand. They did this even after I told them they had to pull the op-rod back and let it go to advance a round into battery. Instead they seemed to think that they had to hold the op-rod and push it home by hand. Something to think about.
