I have some questions about using Briley subgauge tubes in a 12 ga. Parker

Just a word about the Briley Side-Kicks. These were my first exposure to sub-gauge tubes and since they are short and not fitted to the gun's bore diameter there is a large amount of burnt powder residue that comes back between the tubes and the barrel, even though there is an O ring on the end of each tube. You will be doing a lot of heavy cleaning between shooting the different gauges. And then when you're done you will be doing a lot of heavy cleaning to the tubes themselves. They do work okay other than that. Really, the full-length drop-in tubes are the way to go, especially if you're just doing one gauge.
