From NJ.com:

 A Cumberland County man cannot keep his grandfather’s World War II rifle because it is an illegal assault firearm, according to a Sept. 15 New Jersey Superior Court Appellate Division decision.

The M1 carbine could not be returned to him because it falls under the definition of an assault firearm, which is illegal to possess according to New Jersey law.

In a motion filed by Burt, he told the court that he acquired the rifle in 2006 from his grandfather, who served in World War II.
