Semi-automatic rifle

US M1 Carbine semi-automatic rifle

A semi-automatic rifle is a type of rifle that fires a single bullet each time the trigger is pulled, without the need to manually operate a bolt, lever or other firing or loading mechanism. Such a rifle can fire single rounds in this manner until the firearm's supply of cartridges is depleted. They are also commonly known as self-loading rifles ('SLR').

A semi-automatic rifle is distinguished from a fully automatic rifle or machine gun in that it can only fire once each time the trigger is pulled. In some contexts, the term "automatic rifle" may refer to a semi-automatic/SLR rifle, not a fully automatic rifle.

Controversy

In the United States, semi-automatic rifles with a military-style appearance were prohibited from manufacture or importation by the Federal Assault Weapons Ban. Certain U.S. states such as California, Massachusetts, New Jersey and New York have restrictive laws regarding to the ownership and sale of semi-automatic rifles. 

Many semi-automatic-only versions (also known as "sporting" or "civilian" versions) of fully automatic rifles are available, and their external appearance can be nearly identical to their automatic counterparts. However, modern semi-automatic rifles are designed so that they cannot be converted easily to fully automatic fire. In the U.S., BATF regulations require that semi-automatic rifles be manufactured so that they cannot accept parts or modifications that would allow them to be capable of fully automatic fire.
