I ask because I have an idea, since my can is in NFA jail currently I want to mock everything up on my pistol to get a feel for how it's going to feel and to make sure clearances are good. It doesn't seem that you can buy a mock-up can with identical dimensions and weight that's compatable with the mounting system you intend to use. Would it be possible to build something like that, would it be considered a silencer if it contained no baffles, wasn't designed to be used as a silencer, but still reduces noise somehow?
