Full metal (aluminium) silnecer with the 14mm counterclockwise thread. Suitable for the most of airsoft guns. 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. Powered by 4 x AAA Batteries.
Dimension: 145mm x 38mm
