OK, Big 5 seems to have an add in every Sunday paper selling old Mosin Nagants for about $100. This is just killing me. Does anyone have experience doing a home-made custom stock and action (Heck, it's so cheap, you could even do a new barrel...) on one of these? Are they decently reliable and accurate? I mean, the Russians used them for quite a while 'till the AK rolled around.
