Nebraska has no laws regulating semi-automatic firearms or so-called "assault weapons," "large capacity magazines," "ghost guns," bump stocks, or similar items. Machine guns are legal as long as possessed under applicable federal statutes.

Nebraska does not generally regulate or restrict the sale, purchase, or possession of ammunition.

A handgun purchase permit (HPP) or a concealed carry permit is required for the purchase of a handgun in Nebraska.
Neb. Rev. Stat. §§ 69-2403, 69-2409, 69-2410.

The state of Nebraska does not require the registration of firearms.

Nebraska is a permitless carry state allowing a person, other than a minor or a prohibited person, to carry a concealed handgun anywhere in Nebraska, with or without a permit under the Concealed Handgun Permit Act.

Open carry of a handgun without a permit is permissible subject to local restrictions.

Neb. Rev. Stat. §§ 28-1202.01

In Nebraska, the following places are prohibited for carrying a concealed handgun under Neb. Rev. Stat. § 28-1202.01(3):

The regulation of the ownership, possession, storage, transportation, sale, and transfer of firearms and other weapons is a matter of statewide concern and notwithstanding the provisions of any home rule charter, counties, cities, and villages shall not have the power to: Regulate the ownership, possession, storage, transportation, sale, or transfer of firearms or other weapons, except as expressly provided by state law; or Require registration of firearms or other weapons.
Neb. Rev. Stat. §§ 18-1703

Private transferees must obtain either a handgun purchase permit or a concealed handgun permit and are therefore subject to a background check. Neb. Rev. Stat. §§ 69-2403, 69-2404, 69-2431.

A transferee is not required to obtain a handgun purchase permit if:

• The transferee is a licensed firearms dealer under federal law;
• The handgun is an antique;
• The transferee is authorized to do so on behalf of a law enforcement agency;
• The transfer is temporary and the transferee remains: (i) in the line of sight of the transferor; or (ii) within the premises of an established shooting facility; or
• The transfer is between a person and his or her spouse, sibling, parent, child, aunt, uncle, niece, nephew, or grandparent;
• The transferee is a peace officer; or
• The transferee is a holder of a valid Concealed Handgun Permit holder 

Nebraska does not have a specific stand your ground law. State law imposes a duty to retreat before resorting to deadly force in public. 

Neb. Rev. Stat. Ann § 28-1409(4)

Nebraska has no red flag laws in place.
