To manufacture firearms suppressors, you need the appropriate class of Federal Firearms Licence, along with the occupational tax stamp necessary for manufacturing NFA items. Making such a device for a pellet gun is a bit of a thin line to walk - if it's determined to be capable of being mounted to an actual firearm and functioning as a suppressor on an actual firearm, then you've committed a major violation of federal law, and will end up serving time for it. The point of a suppressor on a BB gun is a bit moot, anyhow - there is no expanding gases to contain with a BB gun (this is what a suppressor for a firearm does), so the difference in sound will be negligible, at best.
yes zero one sells an m9 barrel thread that can attach a silencer
If you are asking about the S&W Shotgun. Then NO not at present.
you don't! it is illegal. you cannot even legally have a silencer without a special licence.
it all depends on the make and model. You did not say what kind of BB gun.
Yes I can
Pretty much outside the scope of a hobbyist
You need to Identify the make and model of the BB gun in order to get an answer not the serial number
Any gun can just as easily hurt its owner as anyone else. There are many companies who make BB guns that will last for years
If its a BB Gun, Then Yes.
About 1902.
A BB gun is an Air Gun. Now if you are asking is a BB gun better than an "Air Soft" gun that is different. As for better, well it all depends on what you want it for. A BB gun will do more damage than an Air Soft gun. But that doesn't make it better. basically an air gun has hollow pellets to a bb gun a bb gun has metal balls so they are basically the same gun but with different types of bullets
If translated directly it is 'versagter,' but when used in silencer of a gun it is 'knaldemper.'
