Where can safeties typically be located on a firearm?

Safeties on a firearm are mechanisms designed to prevent accidental discharge and enhance user safety. They are most commonly found on the rear or side of the receiver. This placement allows for easy access for the shooter, making it convenient to engage or disengage the safety without having to reposition their grip on the firearm.

The receiver is a critical part of the firearm that houses the firing mechanism and is generally where the safety mechanism is integrated for optimal functionality. This positioning ensures that the safety can be intuitively operated while maintaining control of the gun.

Other locations mentioned, such as the barrel or the trigger, do not adequately fulfill the requirements for safety access and control. Safeties are not typically found on scopes, as their primary function involves targeting and magnification, not firearm safety.
