    Definitely go with the Lightweight. I recently completed a "Lady Build" which used a BCM LW Middy Barrel and it balances well.

    Lightweight or M4...

    I like a lightweight barrel, personally.

    In your situation, I would get the LW 16" middy, like this one. I didn't see if you specified a gas system, but the middy should shoot a little softer for her and be easier on parts.

    I do not see the point in Govt profile nor M4 profile, both, especially the latter, are pointless- to me.

    It helps, I guess, that I do not shoot accurately enough to notice the possible difference once the barrel heats up.

    Go LW barrel.

    Definately going LW guys! Now, I just have to figure out which gas system to go with. I have never felt a difference between shooting my carbine and a friends middy. Would prefer carbine, just becuase all my rifles have been..

    I would go mid-length.

    There are two reasons why I think mid-length is better on a 16" barrel:

    1) You get the gas port farther away from the chamber, allowing for lower port pressure and delayed unlocking with less stress on parts than a carbine gas setup.
    2) The dwell is shorter. Besides port pressure you also want gas into the action for the correct amount of time. A middy has shorter dwell than a carbine gas setup on a 16" barrel, again leading to less stress on parts.

    That seems to be the consensus among guys here much more knowledgeable than myself. Basically, 14.5" for carbine length gas systems and 16" for middy gas systems is the ideal setup for reliable, soft shooting operation that is not overly harsh on parts. I would not necessarily stick to one gas system just because your other guns are that same gas system. All parts would be interchangeable except for the barrel and gas tube, as far as I know. In my opinion, which is worth exactly what you paid for it, the gas system should be more or less matched to the barrel length, so 14.5" and shorter gets carbine, 16" gets mid-length, and 18" or longer more than likely a rifle length system, although I have read of some issues with rifle length gas systems but can't speak with any authority on the subject.

    Of course, people (including yourself) have been running 16" carbine systems with heavy buffers for a long time, and they seem to work just fine, although by effectively using a heavier buffer as a band-aid you can sometimes end up limiting the range of ammo the weapon can cycle reliably.

    I have a mid-length & a lightweight carbine length 6720, and my vote would be to go with the lightweight. I simply love the feel & balance of it, and I'm sure she would be able to tell the difference as well!
