Hi all, this is my first post, and first rifle. I've just been given a russian capture german military issue k98 mauser. I've done a lot of searching and reading in order to find my answer, but to no avail. My problem is that the safety, when in the half safe position, will engage and fire a cartridge when the bolt is engaged forward and the trigger is pulled. What am I looking at in terms of figuring out what's wrong and needs replaced? should I just disassemble the bolt and look for signs of damage?
