I removed the barrel for easier inspection and cleaning, also removed the barrel shroud/stripper assembly. I couldn’t see the crud in the barrel with it on the gun. I had only ran a few mags. through it before checking/cleaning the barrel. The smooth bore sector was streaked and the rifled sector was caked with lead, it took significant effort and time to get it thoroughly clean. I have shot a tin + since and the barrel is still clean. If it requires a brush I would suggest pulling out the breech o-ring and reinstall after cleaning.
