Gonna take this in a new direction.
Have had SiCo Hybrid with DT bravo mount since 2016. Figured out teflon plumbers tape is the best.
You will want to experiment since as you add carbon from shooting you progressively need less.
The best practice in the case of threading the bravo mount to the barrel, only add tape to maybe 1-2mm threads closest to barrel shoulder. Don’t tape all the threads to barrel end.
You only need 2-4 turns of tape around the barrel shoulder area.
I only wipe the threads with an old Tshirt leaving a little residual oil, no need to get anal about removing all of it.
It doesn’t matter it shreds the tape as you thread the can, or that it bunches up. The idea is to gum upthe works just enough to lock it down while shooting, but not enough you have to ape it off when done.
Teflon plumbers tape won’t burn up or gum up anything a brass or stiff bristle brush can remove.
For the bravo to suppressor thread, I tape all the width of the threads. Since I never disassemble the hybrid, I will do 3-6 turns of tape around the threads. Easy way to do this is thread the bravo to the barrel (without tape), then thread the can to the bravo to get easy tool-less leverage.
Cheap, easy, works.
