No this isn't a suppressor just a blast forwarder it doesn't effect the sound at all. I prevents dust from being kicked up while prone shooting as well if you're running a brake you don't gas the people next to you. No $200 NFA stamp required. But the deal is pending on it.Just for clarification: I still have to run it through an FFL, then wait for a $200 stamp? Correct?
Thanks,
David
