A specific type of firearm conversion device allows a semi-automatic weapon to function as a fully automatic one. This device replaces existing components within the firearm’s trigger mechanism, enabling it to fire repeatedly with a single pull of the trigger. As an example, a standard AR-15 rifle, normally requiring a separate trigger pull for each shot, can, with this device installed, fire continuously as long as the trigger is depressed and ammunition is available.
The significance of understanding this mechanism lies in its heavily regulated status and potential for misuse. Historically, these devices have been associated with increased rates of gun violence, contributing to concerns about public safety. Their small size and relative ease of installation (implied by the phrase) contribute to the challenges in controlling their proliferation and misuse. The unauthorized possession or manufacture of this type of device is a serious federal offense in many jurisdictions.
