The dead air mask is a nice suppressor but a PITA to clean. this one has about 2000 rounds through it. now this is after 30 minutes in the ultrasonic cleaner. hate to see what it looked like before but didn't think about it. just threw it in and turned the cleaner on. it don't knock much of the lead off. have to scrape it off. it does soften it up so it's easier. That stack took a little effort to get apart.
