Can you remove the barrel readily from the Browning Buckmark models like the Camper, Standard, Micro, etc.

The reason I'm asking is AAC sells a suppressor barrel for the Buckmark, and I don't know if it's integral or can be changed out.

It's been a while...I'm almost sure the screw below the barrel, in front on the frame allows removal.
As long as the lug on the new one matches, you should be home free.
Not to forget the top hole, drilled & tapped for the sight base to be retained.

Here is a link to a schematic for the Buckmark:

I am not 100% sure, but I think that all of the Buckmark's share a common design. I have a Target 5.5" and it's design is the same as what is pictured in the schematic, with the exception of the longer barrel having a correspondingly longer top rail that screws on with 3, as opposed to 2 screws from the top.

For the opne pictured, and presumably yours too, screws numbered 57, 59, and 2 are all you need to unscrew to take it down. I would ask AAC about the suitability of their barrel to your pistol, but if it fits one Buckmark, it may fit them all.
