Guess I'll second the motion / state the obvious / add my two cents: I've had a Sumo for a while now for my AAs410 .22 (Sumo is .25) and every time I introduce someone new to airgunning I remove it after shooting a bit. Sounds like a rimfire! then put it back on, almost silent, they are AMAZED every time, every one of them! Thanks Donny ... don't need to try any other make!
