I have an 11.5" BCM pistol
It is their BFH which really just means premium, cold hammer forged barrel. 
As far as I understand it, this is probably their most top-of-the-line set up besides their MK12. 
I have looked on gun broker and cannot find the 11.5" pistol with the cold hammer forged barrel pretty much anywhere. As soon as they get them in stock, they almost instantly sell out. 

SB Brace in FDE, Magpul handstop in FDE, and Surefire 3prong muzzle adapter all included. 

I have put less than 1000 rounds through it. 55gr, 77gr, 62gr. Suppressed and without it, this thing eats everything. 

$1,700
