I've had a lazy eye out for one of these for a couple of years and now I've got a chance to get one. However, I haven't done any home work. Are there any common things to look for with the M1 Carbines that I should know about? Things that could be broken or badly worn but not obvious to the untrained eye? All I know about this one so far is that it's an Inland version and it comes with a bunch of good stuff.
