First, there is no way of answering your question, since there is no information available. Second, you will need to define "license". We get questions from every state in the US, and several other nations. Laws vary from place to place. In the US, MOST states have no requirement for a "license" for an ordinary rifle, shotgun, or handgun.
yes, you can and need a license to own an airsoft gun in nyc.
I don't think you have to have a license to work on guns, but I'm not sure about that. To manufacture guns, you have to have a manufacturers license. Check with the BATF for more information.
Depends on which license, in which area. There is a Concealed Carry License, sometimes called a CHL or CCW or CWP. There is an OWNER'S license required in a few states, such as the Illinois Firearm Owners ID card (FOID) A dealer or collector may hold a Federal Firearms License (FFL) to engage in those practices.
a license
It depends on several factors; Where you are located and exactly what you mean by "gun license." Do you mean a license to carry a gun? A license to purchase a gun? A license to build guns?
Making guns is not illegal. In US, anyone can make a gun that is not fully automatic for their own use without any sort of license, permit, or registration. Making guns commercially (for sale to other people) is also legal, but you have to get a license and pay a tax. Outside of US making guns is also legal in many places, provided you get an appropriate license.
No set number. But if you are "engaging in the business " of buying and selling guns, you need a dealer's license.
Gun laws are dependent on your State. In Texas there is no requirement to register or license guns. A person who carries a gun on their person must have a Concealed Handgun License (CHL), but not the gun itself. It's legal to have a gun in your car without having a CHL.
In the USA it is about 40%, maybe just a little less.
A Curio and Relic license (C&R) is a license that allows collectors to purchase certain guns directly, without going through a dealer in their home state. It is not a license to engage in the business of buying and selling guns, but requires the collector to go through the same background check that a dealer goes through. The license is $30 for 3 years.
No, but a toy license would be acceptable.
USYes. Homemade guns are legal. You may make a gun for your own use provided it is not of a type specially regulated by the Bureau of Alcohol, Tobacco and Firearms without any license. Guns made for sale to others, machine guns, Destructive Devices, short barrel rifles and short barrel shotguns would require either a license or a tax stamp from ATF.
