Hey guys, the other day when I was cleaning my chinese SKS something happend to the safety lever. Befor it would flick up and down like it should have but now it just kinda dangles and doesn't stay in safe or fire position. I dont think any springs or anything fell out when I disasembled it, I looked around the bench and couldn't find anything left over, I've cleaned it several times befor and have never had this problem. Any ideas?
