the round bolt is fine. that was probably added during one of its arsenal rebuilds. The round bolt and the safety lever as apposed to a safety button were considered improvements and all arsenal rebuilds were fitted with them as well as the flip adjustable aperture rear sight. I was lucky enough to have bought a liberated one from an old timer here in my town of residence and it still retains all its original parts except the safety, which i did upgrade to the lever type because i kept mistaking the sfaety for the mag-release and dropping my mag all the time.

The front sights are replaceable with a good brass or nylon hammer and a punch. I beat mine on there with the handle of my ball peen hammer.

Below are some pics of what im talking about. Note the sight is marked RIA. That was the only sight i could find availabe at the time i replaced it. The rest of the rifle is Inland GM sept. 1943...
