The only one of those I have tried is the Gemtech. Friend has one. It's sweet, so I ordered one. I have had three guns threaded while I'm waiting: Ruger 22/45, Beretta M21, Ruger 10/22. My understanding is that there is no disassembly on the Outback. If you absolutely feel the need to clean it, I guess you are supposed to just give it a good soak with mineral spirits (i.e., WD40), and shake it out. First few shots afterwards might be a little smoky. So I'm told, anyway.
