I thought the rules were that you can not add material to a suppressor but removing material was OK.Nevermind, it's illegal. Go figure.
Now you have me wondering, I'll have to read into it some more.I thought the rules were that you can not add material to a suppressor but removing material was OK.
That is how the adjustable suppressors are considered legal. They are listed as full length and the user can remove sections to make them shorter for the application.
It is also why you can not replace a wiper on a suppressor that incorporates a wiper in the design. Replacing the wiper is adding to it. But shooting a hole through a wiper is ok because it is removing material and creating/enlarging the hole.
