Understanding New Jersey Assault Weapon Laws

New Jersey regulates certain firearms under what the law refers to as “assault firearms.” These regulations restrict specific firearm models as well as certain combinations of features that may be present on semi-automatic firearms.

Because firearm laws can vary significantly between states, gun owners who move to or live in New Jersey should understand how the state defines and regulates these firearms.

This guide provides an overview of how New Jersey assault firearm laws work and what gun owners should know.

What features are restricted on rifles in New Jersey?

Certain features on semi-automatic rifles may be restricted under New Jersey law depending on how the firearm is configured.

How New Jersey Defines an “Assault Firearm”

New Jersey law defines an assault firearm in several ways. A firearm may fall under the state’s definition if it:

  • is specifically listed as a prohibited firearm under state law
  • is substantially identical to certain listed firearms
  • includes certain restricted combinations of features on semi-automatic rifles

Because these definitions can be complex, firearm owners often review the state statutes or consult knowledgeable firearm dealers when determining whether a firearm complies with New Jersey law.

Restricted Firearm Features

New Jersey law regulates certain features on semi-automatic rifles. Depending on the configuration of the firearm, specific combinations of features may be restricted.

Examples of regulated features may include items such as:

  • folding or telescoping stocks
  • certain flash suppressors
  • grenade launcher mounts
  • certain bayonet lugs

Because the legality of a firearm can depend on its specific configuration, gun owners should review applicable state statutes and guidance before purchasing or modifying a firearm.

Magazine Capacity Limits

Separate from assault firearm regulations, New Jersey law also limits most firearm magazines to 10 rounds of ammunition.
This magazine capacity limit applies to many types of firearms including rifles and pistols.

Firearms That Are Specifically Listed

New Jersey statutes include a list of specific firearm models that are defined as prohibited assault firearms.

The list includes certain named firearms and also covers firearms considered “substantially identical” to those listed models.

Because firearm models and configurations vary widely, gun owners often verify firearm compliance before purchasing or transporting firearms within the state.

Why These Laws Can Be Confusing

New Jersey’s firearm laws are among the most detailed in the country. The definitions used in state statutes and related guidance can sometimes be difficult for new gun owners to interpret.

Understanding the applicable firearm laws is important for responsible firearm ownership and compliance with state regulations.
