Does anyone know what is the size on the 14.5" issued and on the 16" sold to civilians?

.063 is the size on both, the 14.5" AND the 16"?

Thanks. Technically, shouldn't the size be smaller on the 16" to compensate for the extended dwell time?

???

Also, does anyone know if DD or BCM have different or same gas port sizes on 16" vs 14.5" carbines?
