Is the barrel the only difference if I wanted to convert a tamiya JSU-152 kit to a JSU-122 or 122(s)?

Yes, and the same is true for the 122S (which they made a TON of......) Different mantlets though.

Not quite, the ISU122 had no muzzel brake, the ISU122S with the different mantlet had one.

Tony- I was referring to the different mantlet on the ISU-122S, not the ISU 152 compared to the ISU 122. The Russians actually made more of the 122S than the 152!

I'm refering to the ISU-122 and not the 152. The original ISU-122 had no muzzel brake and the ISU-122S did, just like on a IS-2.

I ordered and fit the CMK ISU-122 A-19 barrel and have been trying to fit it just right. Mine protrudes just abit more than I think it should, but then again I have seen mixed photos so I might just keep it as is.

He is stating that the mantlet is different on the ISU-122 and the ISU-122S, the barrel was not the only difference.

Now the ISU-152 and the ISU-122 shared the same "chin" mantlet. The ISU-122 also was the A-19 gun the ISU-122S with the round mantlet was a D-25T like on the JS/IS-2 and yes, it did have the muzzle break.

Yes, that was the point I was trying to make. The 122 had the A19 gun in the same mantlet as the 152.

JHunter- Nice model! THats the new Tamiya kit, right. Love to see more pictures....
regarding the length you should seat the barrel flush with the mantlet and it would be ok I think. I dont have exact length measurements on the barrel. ISU-122

Yes, that's what I stated above. Here, I'll post it again.

The ISU 152 and the ISU122 have the same mantlet. The ISU122S has a different mantlet and barrel than the ISU122.
