I think the point folks are making is valid, most of the suppressors I’m familiar with (admittedly only a handful, although I think these are the go-to ones for a centerfire hunting rifle now) are exactly the same regardless of whether you are using a hub-style adapter or a direct thread. By that I mean the hub vs direct thread part are both identically threaded to the can itself, and the hub adapter on gun is also threaded just like a threaded adapter on the gun taking it from 1/2 to 5/8, so “same” quantity of tolerances regardless of what system you use. After just having shopped for a new can, NONE of the cans I looked at eliminated a tolerance by using a hub style adapter. On the contrary, the can I ended up buying, if you use that brand‘s hub style adapter, you actually ADD a tolerance assuming your barrel is directly threaded at 5/8 24.
Are manufacturers making cans with a larger bore to accommodate the stacking of tolerances though? Of course they are. manufacturers make cans they can sell to as many customers as possible, and if one of those adapters is out of their control, they have to decide how much wiggle room to build into the bore size to account for their own tolerances plus avoid problems with other parts in the system. However, I’d be tempted to say that buying a .308 caliber can, and shooting a .264 or .284 bullet through it, makes a far larger difference than whatever allowance they provide for a poorly threaded adapter, but that’s just conjecture.
Regardless, folks can’t even agree on how loud individual suppressors are, or even how to measure them, so I highly doubt anyone can say this effect is universal or significant one way or another with any authority.
