Does a 14.5-inch AR-15 barrel require a permanently attached muzzle device?

A 14.5" barrel by itself is shorter than the federal 16" minimum barrel length generally applicable to a non-NFA rifle. A qualifying muzzle device may be permanently attached to bring the measured barrel length to at least 16". The exact configuration matters, so check each Moriarti 14.5" kit listing to determine whether its muzzle device is permanently attached and whether the listed configuration reaches the required overall barrel length.
