They have been sued for shpping to states that outlaw silencers.
Upon launching the Maxim 50, SilencerCo received several immediate legal challenges from authorities and lawyers in the states of New Jersey, Massachusetts, and California. Since we have no desire to place any consumer in a situation where they may get arrested and charged with a felony because their state defines a
firearm differently than the Bureau of Alcohol, Tobacco,
Firearms and Explosives (BATFE), we have placed orders from those states on hold and are refunding customers pending legal confirmation. We will update our customers as soon as we have multiple source verification.
