Nick,
I'm using the BCM 14.5" Middy for my duty weapon, and it is the smoothest shooting setup I've ever used. I'm clearing buildings with it on a regular basis, and am very happy. Note the below picture is the upper, but my duty layout is with a CTR and Aimpoint M4. I also use a handstop, not a VFG. I'm using a ST buffer which is pretty heavy, and no problems of any kind. I would imagine weaker loads would be fine with a lighter buffer if needed.
I wrote up some info about it for Military Times, it might be worth a quick read.
