LCT ZDTK-19 PP-19-01 Silencer With Tracer Unit, Silver

The real problem with tracers is mounting them. Your rifle runs 14mm CCW. Your pistol or AK runs something else. The tracer you want only fits one. The ZDTK-19 is a mock suppressor with an integrated green tracer unit, and it threads at both ends so you can pick the right one: 14mm CCW for the standard rifle setup, or 24mm CW for pistols and AK-pattern platforms. One unit covers both.

Once threaded on, the green LED illuminates each BB as it passes. You can see the arc mid-flight, which is useful for range estimation in low light, milsim night games, or just watching a shot land on a steel target. It does not affect velocity, chronograph numbers, or accuracy.

The unit is aluminum and steel, silver anodized, and weighs 0.44 lbs. Light enough that it will not throw off balance on a carbine, solid enough to not feel like plastic filler on the end of a barrel.

Wiring. The tracer is electrically powered. Installation routes wire through your barrel to your battery port, so check whether your gun's battery connector matches and whether you have room for the additional lead before you buy. The exact wiring method depends on your gun and your battery setup, and LCT provides installation guidance with the unit.
