Yes, but don't expect to go to your local gun shop or gun show and buy one.
They are very expensive and are in limited supply. You need to be 21 years old if you wish to purchase a true assault rifle, which would be an NFA taxed stamped select-fire Class III firearm capable of full auto function. Buying NFA items is NOT easy. Full auto rifles are very expensive and there is a limited supply available to the public (your local gun store or gun show WILL PROBABLY NOT have any). Full auto capable "assault rifles" ARE NOT being bought at gun shops and gun shows in the US and taken to Mexico. All NFA items must be registered with the Bureau of Alcohol, Tobacco, Firearms, and Explosives (ATF). Private owners wishing to purchase an NFA item must obtain permission from the ATF, obtain a signature from the county sheriff or city or town chief of police (not necessarily permission), pass an extensive background check (including a NICS), submit a photograph and fingerprints, fully register the firearm, receive ATF written permission before moving the firearm across state lines, and pay a tax ($200). While an individual owner does not need a NFA dealer license to buy Title II firearms. A licensed Class III dealer would have to receive the rifle for you before it could be transferred to you.
In California, the Colt AR-15 is subject to strict regulations under the state's assault weapons ban. Generally, semi-automatic rifles that meet specific criteria are classified as assault weapons and are illegal to sell or transfer. However, variants of the AR-15 that comply with California's features test and are registered may be legal to possess. Always check current laws and regulations, as they can change frequently.

It depends on what you mean. Most people use the term assault rifle incorrectly. If you mean an AR-15, that is not an assault rifle. That is a semi-automatic magazine fed rifle, or, in current terms, a modern sporting rifle. AR-15 rifles are legal in every state in the U.S. as far as I know. Real assault rifles are legal in most but not all states, under certain restrictions.
In New Jersey, legal rifles are generally defined as firearms that comply with state regulations, which include specific restrictions on features and configurations. Semi-automatic rifles with certain characteristics, such as detachable magazines and pistol grips, may be classified as "assault firearms" and are prohibited. Legal options typically include bolt-action, lever-action, and certain semi-automatic rifles that do not possess banned features. Additionally, all firearms must be registered, and owners must possess the appropriate permits and licenses.

You need to contact the NYSP for a current and correct answer.
So long as the firearms they're transporting are legal at their destination, yes.
It depends on the gun and caliber but most semi-automatic rifles such as the Ruger .22 are legal to hunt with in California.
Yes
Gun laws and regulations very from state to state. In many states, as long as one is properly licensed and certified, they can carry many handgun, shotguns and rifles but are not allowed to own assault type weapons.
