If I was in fact making a controlled weapon, witch I am not. Im not making anything illegal according to the and will be doing everything I can do to make sure they are not.
Laws are here to protect us too. Just because they can bust in dosnt mean its right or they will get away with it. "intent" is the big factor. If I want to make firearm suppressors I can do that legally at work.
I would be worried if I was really breaking the law but I am no more breaking the the the makers of PVC pipe, or mufflers.
