Also called a silencer, these are legal in the US, but regulated by the same agency that handles machineguns. PART of the noise created by a gunshot is the shockwave created by the expanding gasses from the burning gunpowder. A suppressor captures most of the gasses in a system of baffles or chambers, slows and cools them, and releases them gradually. They do not truly silence a gunshot, but they can reduce or suppress much of the sound and muzzle flash.
The Maxim suppressor was made of steel.
Suppressor
Sometimes it will.
Yes, in general a suppressor can increase rate of fire by 50-100 rounds/ minute.
While not designed to make a gun louder, a muzzle brake usually has that effect.
You have to make one
If you have the time and money, you'd need to make a suppressor from scratch, since the average Thompson was not able to fit a suppressor.
YES! Any firearm that doesn't use a suppressor (silencer) will have a loud sound.
By allowing the gases to expand in a controlled fashion.
Usually suppressors can be screwed on, so there should be notches to screw it on.
No there is nothing like that.There is a pistol and a automatic hand gun Glock.
Depends on the suppressor. Many are made to be taken apart, soaked in solvent, brushed, and reassembled.
