In another thread, rushca01 mentioned his SWR Trident 9 that had been "jailbroken" by ECO machine. I only have two suppressors, a AAC TiRant 9 and a Bowers Bitty, so I really don't know much about suppressors. It seems to me that you'd want to clean a suppressor every once in a while because they get dirty. Why would a manufacturer design a suppressor that can't be cleaned? Does it have to do with performance, manufacturing ease or something else? If you want a suppressor that can be cleaned, why buy one that would have to be modified by someone else in order to allow you to clean it? Is it a didn't realize it couldn't be cleaned kind of thing, is the suppressor just that good, or is it something else? I do know that my TiRant 9 was a major pain in the rear to clean. I literally had to pound it apart using a wooden dowel. I've never cleaned the Bitty because the instruction included with it recommended against it.
