Couldn't find anything in the search... The block on top of the action is rounded on the corners, also the bottem of the bolt where this block fits is rounded on the edge. Hence, the bolt *pops* out from time to time. If i grind it away i am worried that the action will be sloppy... not good. Should i get new parts (if avalible) or grind and JB weld it?? Also it was my great grandpa's rifle, i dont want to slaughter it haha.
