just take a brass rod and mallet and tap the front sight left or right in it's mortise....you may have to use some lube like kroil to get it to budge if its stuck. mine was a bear and after beating on it forever i finally got pissed and took a propane torch to it thinking it was only a $150 gun and im gonna make it move if i break it or not....to my surprise and my wifes laughter i got the front sight assembly red hot and whacked it....and whalah it moved and now works fine. not to bad on a chineese gun so i thought......just as a side note.....i didnt hava tool to adjust the front sight for elevation one day so i picked up a 223 case on the range....squashed the case mouth ever so slightly into a oval and it fit and works great......not bad for a free sight adjustment tool.
