I think you will have to check with the local law enforcement in order to get that answer. I know that just as long as you have the orange tip on the gun, it makes it legal to distribute in the U.S. If you can have one, check out Airplsat.com. It's where I get all my stuff and I love the website.
You never need a license to have an Airsoft gun.
You need a Firearm Purchaser's ID card- a form of permit. NJ has a LOT of gun laws.
An Airsoft gun
A pump airsoft gun is a gun that has to be pumped every time before shooting. Ex. Airsoft shotgun
Buy an new one or take it to an airsoft shop or army navy.
Depends on which gun you are buying, but in general, yes, it is. Contact the New Jersey State Police for additional information. This is a fairly complex process and takes several months to complete.

I would get the JG MP5 SD6 Airsoft Rifle AEG Gun 067. It has excellent performance and is great for a beginner.
No
It is an airsoft gun based of the PPSH-41 gun
buy a new screen.........................
Ahh figure out what the problem part is than figure out how to take the gun apart and put it back together from YouTube, an airsoft forum, or from an airsoft website. Than buy the replacement part and put it in the gun. If the gun was bought for under $100 than you would be better off buying a new gun instead.
