My cousin said he would sell me his mini 14 for $700 its in great condition he has a couple awsome stocks for it and some good magazines with a descent scope. My question is because i dont know.much about them but have wanted one for a while is that a good price? My concern is when i shot it a round every know and then did not fire and by examining the round it appears to me that the firingpin did not strike the primer hard enough to ignite it. Has anyone heard of this problem? Is it fixable? Is it worth buying if he doesnt fix it before i buy it ?
