The Tracer Unit is an accessory that attaches to your barrel like a mock silencer. Inside the metal tube it has a sensor that will notify the unit to light up if a bb is detected. The lighting device inside will illuminate glow in the dark BB's and cause them to glow leaving the barrel. For those that have never seen a tracer unit in action, it is probably one of the coolest things in Airsoft as each BB will travel like a comet with a tail. This device is modeled after the military tracer unit used to determine your bullet's path at night.
Fits all 14mm negative thread Airsoft guns. (Pretty much all models will work, some rare models and Positive thread guns need an adapter.) Feel free to consult with our technicians if you have any questions.
Power: 4 x AAA Batteries (not included)
