Ryohin Buhin 5KU Muzzle Flash Tracer Unit for Tokyo Marui M870 and Benelli M3 Shotguns, Glow-in-the-Dark Bullets, 23.5mm Diameter

Compatible Air Guns: ■ Shotguns/rifles with outer barrel tips between 22.5mm and 23.5mm (Tokyo Marui M870 Shotgun, M3 Super, etc.) *When measuring the outer barrel diameter of a shotgun or rifle, measure approximately 10mm from the tip. *If the outer barrel diameter is smaller than the indicated size, it may be possible to attach it by thickening it with tape or something similar. This tracer unit can be attached to unthreaded shotguns. It has a built-in battery, so you can use it immediately after receiving it and charging it. It has a built-in 5W UV (ultraviolet light source), so you can enjoy tracer-like trajectories by using special glow-in-the-dark BBs. *Special glow-in-the-dark BBs are required to use the tracer function. The most notable feature of this tracer unit is its muzzle flash function! When the sensor detects a BB passing through, the tip of the tracer flashes. Using it in dark places provides an even more intense shooting experience. To prevent battery deterioration, the device has an auto-off function that automatically turns off the power after 5 minutes of inactivity. After auto-off, the vibration sensor activates and the device automatically resumes operation with a slight shock.
