Hi m657 The barons den in eugene has one. You will still have to scrub out your bore, take your grips off blow the gun out with compressed air and relube it. All so I did not find where it cleand the gun all that well.
I use mine for cleaning brass. Never tried it on a complete gun. I definately wouldn't spend $400 on one. Ultrasonic is ultrasonic and the main difference in the costs is the size. I bought mine in San Antonio at Harbor Freight for about $65 or $75 and it works very well on cleaning brass cases.
