A friend bought a 03-A3 yesterday. He shot it this morning and had difficulties with the bolt. The bolt is hard to close, like it wants to hang up and needs several attempts or a rather stiff push or hard thrust to close. Rifle is like new. Doubt it has had more than 50 rounds though it. Will post pictures latter. Best guesses as to the problem. We do not see and shiny spots or scoring on the bolt that would give us a starting point as to the problem.
