Adding a firearm silencer or suppressor to your rifle or hand-gun can greatly improve the pleasure of your shooting experience. Over a long period of exposure, shooting can permanently damage your hearing – even if you are wearing firearm hearing protection.
Homemade gun silencers are not difficult to build for most types of firearms. You can build a homemade rifle or pistol silencer in a small home workshop.
Be certain to check all applicable Federal, State, and Local laws before purchasing, building, or installing a gun silencer or suppressor.

On the Control of Silencers in the United States
In 1934 a bill was passed levying a tax of $200 (4 times the price of a Thompson submachine gun at the time.) on future sales of machine guns. Short-barreled rifles and shotguns, cane guns and silencers were also thrown into the bill, almost as an afterthought. The BATF was set up, and one of its functions today is to collect such a tax. So much of the controversy dealing with Title II weapons is not that they are illegal, but that a tax will be levied on their ownership. Owning one which is not properly registered and taxed is a violation of federal tax code (tax evasion) a felony punishable by large fines and up to ten years in prison.
