 A well made shroud of the same Dia and the same projected length past the end of the barrel  should easily out perform a similar moderator. The reason being the air is able to expand in the space between the shroud and barrel, this slows the air as it finally exits the endcap.

i made this for my grandson, 35mm Dia, 500mm long (125mm past the end of the barrel). Genuinely, the noise from the pellet tearing through a paper target at 30 yards is louder than the muzzle report. This is by far the quietest airgun I have every heard.


Another advantage of the shroud is it adds stiffness to the barrel, this can aid accuracy, the disadvantage are, you will need higher scope mounts for clearance and being fatter for longer, a shroud is more difficult to keep under control in the wind.
