What is an AR-15 select fire switch?

An AR-15 select fire switch, also known as a selector switch or safety selector, is a mechanism that allows the user to choose between different firing modes on their AR-15 rifle. The most common modes are safe, semi-automatic (meaning one shot per trigger pull), and automatic (meaning multiple shots per trigger pull). This feature is present in fully automatic rifles used by military and police forces.

The purpose of the select fire switch on an AR-15 rifle was originally designed for military use as it allowed soldiers to quickly transition from single-shot mode to full-auto burst when needed. However, it has now become a controversial issue in civilian gun ownership due to concerns over safety and regulation.

When engaged onto full automatic mode; Pulling back on trigger lever will cause multiple bullets rounds fired consecutively due rapid cycling of internal parts until magazine gets empty; changing rate-of-fire depending upon setting chosen by user.
