If you understand this and select a muzzle device that will index on the muzzle not the shoulder then it's not a problem.
Selecting a barrel that is larger at the muzzle end but the same under the handguards to reduce POI shift seems odd to me.
The number of people who shoot suppressed only rifles is very small, that's why there are no rifles made that way. Rifles with suppressed only gas ports should not be considered reliable without the silencer.
