I just got my hands on a PSA 16" light weight profile upper. I was planning on making it into a dissipator running a magpul MOE rifle length handguard, but the O.D. of the barrel is 0.675"

All I can find are 0.750 or 0.625 front sight posts. Anyone know if these are made anywhere, or a machinist in the East Bay that could drill a .625 FSB to .675?
