Abstract: A tracker for a firearm comprises a device capable of being secured to a Picatinny® rail of a firearm. The device is in wireless communication with a smart electronic device thereby alerting a user of when the firearm has been moved. The device also comes with an audio alert which issues forth a high decibel and painful sound to dissuade unauthorized use.
