No suppressor.
Notice the barrel doesn’t take long to get copper build up..

if you are getting heavy copper fouling after only 10 - 12 rounds then apart from removing the Cu with a quality solvent (I use Boretech Eliminator, and KG12 is very good too but does not show the blue colour so harder to track how you're going) .... but after Cu & carbon removed you might want to consider lapping or polishing bbl with Autosol or JB's Borepaste. Dont go over board with it, use small amount (pea size) and only 5 - 6 strokes up/down bbl. then remove/clean thoroughly with Hoppes or similar solvent.
