I find myself wondering how we have gotten to a place in this country where innovations for ways to reduce noise from a firearm involve the ATF. Seriously don’t understand what the issue is or why they need to be regulated. I have seen people use oil and fuel filters, PVC, etc and the government says it is illegal. Why? What possible argument do they have for noise reduction other than taxing it to further irritate us. So our best option is to buy an overpriced “legal” suppressor and wait.
