Which of the following is a common type of non-restricted firearm?

A common type of non-restricted firearm is a rifle. Non-restricted firearms are defined as those that are not easily concealable and do not fall into categories specified under stricter regulations, such as prohibited or restricted firearms. Rifles, which are designed for accuracy over longer ranges and are typically longer than handguns, fit this definition well.

In many jurisdictions, rifles are considered non-restricted as they are widely used for hunting and sport shooting, making them more accessible to the general public. Pistol and revolver types are generally classified as restricted firearms in many areas due to their concealable nature and potential for use in crimes. Machine guns, on the other hand, are classified as prohibited due to their capability to fire multiple rounds rapidly without needing to be reloaded.
