I built this upper a couple of months ago and it has proven to be extremely accurate and 100% malfunction free.
Specs:
BCM upper w/M4 feedramps
BCM bolt carrier group (MPI) - Auto
Centurion Arms hammer forged barrel - 16" - 1:7" twist - M4 feedramps - midlength gas
YHM low profile gas bock
Troy Inustries/Viking Tactics 11" extreme battlerail (free float)
It cost me roughly $800 to build this upper. I'll sell it for $685 shipped in the CONUS. 100-150 rounds through it.
