I'm working on the baffle design to make my own can(s)... I want to have one (or at least one per) for my AR15 pistol(s)... The ultimate 'home defender' with 30 rounds of either .223/5.56 NATO or 300 Blackout in a mag.
Got to love living in a free state. IF I do end up making a can (or more) it will only cost me the $200 for the NFA tax stamp to make them legal. Far less than you'll typically spend.
For those living under the thumb of suppressive governments... Sucks to be you.
I actually do feel bad for you though. I'm just glad I was finally able to escape (at least living there).
