For the first time since the National Firearms Act (NFA) was created in 1934, civilians can enjoy suppressed shooting in all 50 states with SilencerCo's latest innovation: the integrally suppressed Maxim 50 muzzleloader. In addition, this product can be purchased right now on the web with no regulation (no 4473, no $200 tax stamp, no photographs, and no fingerprints) and be shipped immediately to the customer with few exceptions.
Kinda spendy at $999, although noteworthy of the idea behind it.
