I was looking at BCM uppers yesterday. Are their bore's chrome lined?The only thing it specified on the site was Magnetic Particle Inspected which I guess is like Magnafluxing an engine.
I've heard good reports on them and they are fairly reasonably priced.
Can anyone educate me on this subject?? Thanks
