The Acetech Predator S Tracer Unit is for use on airsoft guns that have a 14mm threaded (for use on CCW or CW) barrel. A tracer unit is used to make your BBs brightly glow in the dark as they fly out of your gun! A very cool night effect. The Predator S is just a different design and is slightly shorter than the L series.
Metal outer construction for reliability and durability on the airsoft battlefield. The tracer module uses 4 (four) AAA batteries to power the unit. There's a power savings mode, standby, and auto power-off if you accidentally leave it on for too long. For use on guns up to 1800 RPM.
35mm x 155mm length. 153g weight w/o batteries.
For use with all glow in the dark tracer airsoft BBs 6mm.
