You're fortunate that you can buy from out of state. In CA, we can only buy stuff that is already in state, so there are few bargains. So, in that box, it's probably the old GI Mil Spec without the lowered and flared ejection port, relieved barrel, and polished ramp - But with a throated barrel. Funny thing is, some people will pay a premium for those because it looks just like their issue gun.
In fact, the throated barrel is the one option that is actually important. I'm going to commit heresy right now and say that lowering and flaring, relieving the barrel, and polishing the ramp contribute nothing to the function of the gun. I've done the experiment... And it makes sense too, because Browning designed it to be both accurate and reliable. But he did not design it to feed hollow points and wadcutters.
So, why do all the guns sold now have all of these accuracy and reliability improvements? Blame it on Kuhnhausen. What's funny is that folks "diss" Kuhnhausen for recommending the FLGR and ShokBuf, both of which do improve the handling of the gun, but believe that these other mods, which do nothing (unless the gun is very poorly made and fitted - Certainly possible - The more I play with my Armscor Citadel Compact, the less happy I am with it), are required.
