You're wrong. The BCM barrels are cold hammer forged and are the same quality as the Diemaco barrels, maybe even more because of the nicer finish. I own one of those BCM C8 uppers and I use the C8A3s. When I got my upper last year I even brought it to work and stripped it straight out of the box and compared it with a stripped C8A3.
BCM has to be one of the best AR-15 producers out there.
I also own one of the BCM uppers, I stand corrected, it is hammer forged. It is still over 16" in length. I am well aware of BCM, I have a few complete carbines and they are well built.
