Facing an upper receiver ?
I have used the search function on this with very little information gathered other than it is a feel good measure.
I have a BCM4 upper on the way with a Brownells facing tool also.
Thinking facing is a good thing to have receiver face square for proper barrel installation and equal bolt lug engagement.
Am I on the right track ?
Building a precision upper for bench rest and prone shooting.
Taking my time on this build, maybe a year.
Currently looking at barrels, specifically the Lija at this time.
