I've seen some stuff in my life, but never this.

is nice about it freedom from head clampa and objects jammed in ears, and almost as "free and natural" as bow hunting when hunting suppressed. I simply dislike the extra bulk, and declining years making ability to get around in woods harder and harder, while at a range the protection still a must due to other shooters, and I live in town and no shooting in yard due to law a safety worries for others.

As for cleaning that cited gizmo, if well designed, a quick disassembly and throwing in an ultrasonic cleaner would likely make it one of the easier gun cleaning chores.
