Small Arms Fire Control Selector

Small Arms Fire Control Selector refers to a mechanism found on firearms that allows the user to select the firing mode or function of the weapon. It is typically located near the trigger or on the side of the firearm and can be manipulated by the shooter's thumb or index finger.

The most common types of fire control selectors include:

1. Safe: This position ensures that the firearm is in a safe state and prevents accidental discharge. When the selector is set to "Safe," the trigger is usually locked and cannot be pulled.

2. Semi-Automatic: In this mode, the firearm fires one round with each pull of the trigger. After firing, the trigger must be released and pulled again to fire another round.

3. Burst: Some firearms, particularly military rifles, have a burst fire mode. In this mode, a predetermined number of rounds (usually 2 or 3) are fired with a single pull of the trigger. This mode is often used for controlled bursts of fire to conserve ammunition and improve accuracy.

4. Full-Automatic: This mode allows the firearm to continuously fire as long as the trigger is held down. It is commonly referred to as "full-auto" or "fully automatic." This mode is typically found on military-grade weapons and is heavily regulated or prohibited in many countries.

It's important to note that the availability and legality of different firing modes may vary depending on the firearm type, local laws, and regulations. Always ensure that you are familiar with the specific firearm you are using and adhere to all applicable laws and safety guidelines.
