I have a friend who's thinking about some day getting an M14/M1a, and I'm wondering what's to know. I'm vaguely familiar with the differences between the Chi-Coms and the domestic ones. Is there a distinct difference between Fed Ordnance, Springfield, and others? I've recently seen a pre-ban Fed for 1000ish, and my friend would probably want a pre-ban. Any functional differences between pre and post ban? Do any new ones come with bayonet lug OR flash hider, as opposed to the older ones with both? And can any still be loaded with strippers?
