Generally speaking, it has baffles inside that trap the gases. See the associated link for diagrams. ADDING: Oh, and silencers are not really "silent" either. Most of them make a powerful gun sound like a cap pistol. Some of them make a handgun or .22 sound like a CO2 powered pellet gun. I own a silencer and I have personally shot several others and witnessed several others on various kinds of guns being used right next to me at shooting ranges.

Making a .22 supressor without a license is a federal crime.
It depends on what you mean. A .22 caliber gun is a gun that will fire a .22 caliber cartridge. If you want an example of a .22 caliber gun, one example would be a Smith and Wesson model 17. this is true but u must remember that when describing a caliber u are talking about the diameter of the round . for example the .22 long rifle is the same diameter as the 5.56 that the m4 shoots . if the round is refer ed to as the .22 it will most likely be rim fire as other .22 like 5.7,5.56,and.223 will be center fire
It all depends on the gun and its specs like the guns velocity.
