Is the sporter Accustock exactly the same as the heavy barrel Accustock?

Is the current sporter barrel Accustock exactly the same as the heavier barrel Accustock? 100% the same, even the barrel channel width? Or is there a sporter Accustock and also a varmint Accustock?

I plan to buy a sporter barrel version, then upgrade the barrel to a custom semi-varmint kinda like the Predator Hunter version, not a full varmint barrel, kinda half way between sporter and varmint. I'd just buy the Predator Hunter Max-1 model but I don't want the camo stock. I could sell the camo Accustock but there aren't any similar aftermarket replacements.

Just wondering if the sporter barreled version of the Accustock will work, or is there a different Accustock for the wider barreled models? And which model should I start my build with?

Thx.
