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.
