I am sure you know barrels are usually measured with the bolt locked in and rod inserted down the bore and measured at the muzzle. I usually subtract at least an inch on the rail as compared to the barrels measured length if I want it close to the barrel shoulder where the threads start for the muzzle device.
Then there is the crap shoot of rail manufactures that list a length but it isn't measured true (or at least true to how I may measure), use to be an issue with MI as they would say a rail was 12" when it actual was 12.25" but they changed that issue up a while back. Let's not start on the 100+ different shades of FDE, nobodies ever seem to match anyone else's ever. I painted a fde stock just so it would match my other parts, at least it has a similar base color when it get's scuffed up from use.
