Illegal Guns in Maryland and Copycat Weapons

Maryland does not allow the possession of assault weapons, high-capacity weapons, or copycat weapons.

A copycat weapon is any weapon designed to mimic a banned weapon under a different name. For example, an AK-47 is a banned weapon in Maryland; a copycat weapon is any weapon that acts like an AK-47, such as being semiautomatic with a detachable magazine. Copycat weapons may not be possessed, sold, or transferred in Maryland. 

For law enforcement purposes, Maryland considers a firearm a copycat weapon if it is both cosmetically similar to a banned weapon and has interchangeable internal components that meet the full operation and function of the banned gun. The ultimate determination is left up to the arresting officer at the time. It is advised to contact a firearms attorney in Maryland ASAP if you were found in possession of a copycat weapon. Due to the gray areas in Maryland law, Saller Law may be able to assist with your charges. 

When purchasing a firearm in Maryland that you are unsure of, it is best to assess your gun based on its features and actions vs a list of named banned weapons. It is advised to contact a reputable firearms dealer to consult on any weapon you are considering purchasing in Maryland.
