Nomadic Pirate, muzzle velocity, is 1,050fps, and 901 at a hundred yds. Be very careful with the soda bottle, and duct tape. It is illegal to manufacture, or be in possesion of a homemade suppressor.
You can buy them, but you cannot manufacture them, without a class 3 license. You can purchase them, plus a $200.00 tax stamp fee, after a background check. There are different ways to apply for them. I used the revocable one party living trust.
You have to purchase a new stamp for each additional suppressor. But if you do decide to take the risk, and use the plastic soda bottle, and duct tape, a bolt action is better.
