i called the courthouse and said i would just pay the fine =(
5zigen makes a silencer that supposedly fits all their NA applications. . .36 bucks shipped from one of their authorized dealers. . .
I decided that since 5zigen isnt legal here, it would better for me to just pay the fine than to spend 36 dollars on a silencer based on the idea that my interpretation of the law is correct. . .they could have told me to go f u c k myself and id have paid 86 dollars instead of the 50 for the citation. . .oh well, if it happens again, im gonna talk to a lawyer and then fight it. . .
