I think you would get in more trouble when the police not only find your shooting a pellet rifle at night and waking up your neighbors... but also have an illegal suppressor on it. :lol: There have been issues with suppressors being legal or illegal for "Air Soft Guns" and "BB Guns" (including pelet rifles). I would error on the side of caution and stay away from supressors all together... unless you get one legally.
