This is almost the same style suppressor that works on airsoft or .22LR, with standard rounds. I can't see this making it to market. Didn't GSG have to change the fake suppressor that came with the 1911 pistol as the RCMP deemed it to easy to mod?
I have seen this one, the longer version, with holes that go all the way through to make it act like a flash hider/comp. Don't know if it's legal though.
