No - they're normal barrel-shaped.

Naturally I would defer to clarification from the poster, but it seems to me that the question is in regard to the shape of the bore...... a more interesting question. Meonig Barrels are known for their "reverse taper" which is larger at the top of the barrel becoming more narrow as it enters the top joint of the clarinet. I have always assumed this means the standard Buffet barrel features a smaller entrance at the top and a larger exit diameter.
As another example I believe I have been told that the Yamaha CSG barrels are not only much shorter (with the missing length provided by the longer top joint of those clarinets) but are also internally just a straight cylinder.

Yes, that is exactly what I mean (thank you, Paul Aviles!). As far as I understand, the bore of a barrel makes a considerable difference. Chadash, Moennig and others are reversed conical. This may bring advantages, or maybe not.
Could someone clarify me?
And what is the internal shape of Buffet barrels that come with the instrument? Are Tosca barrels internally shaped, or they are basically a cylindrical tube?

I've not measured a Tosca barrel, but the following Buffet original ones:
- Tradition 1 Bb, barrel marked "B65" (length 65mm), upper end: 15.37mm, lower end: 14.82mm (thus a reverse taper)
- Tradition 1 A, barrel marked "A65" (length 65mm), upper end: 14.96mm, lower end: 14.94mm (thus cylindrical - a few 1/100 mills up or down can be due to measurement uncertainty, and often there is also some ovality within this scale so that measurements taken at different angles differ up to a few 1/100's)
- Buffet E-11, barrel length 64.2mm, upper end: 15.01mm, lower end: 14.91mm (thus a reverse taper, but a lot less than on the Tradition Bb above)

Many barrel designs have a cylindrical section of greater or lesser proportion of the bore, with "cones" at either end. This is clearly visible to the naked eye on my Zinner 66mm barrel but the cylindrical section is only about 1/3rd of the bore. Another barrel I have was measured by an instrument maker, who discovered it was almost entirely cylindrical, with a slight conical section at one end where it joined the upper joint.
Anyone who measured this JUST BY MEASURING THE ENTRY/EXIT would completely miss the fact that the bore was almost entirely cylindrical.
