The SixNeedler Tracer Engine is a muzzle attachment for the SixNeedler Needle Revolver that adds light effects to each shot. It flashes in one of six selectable colors and charges glow-in-the-dark tracer darts so they glow briefly after firing. It suits owners who want visual feedback and a custom look for their SixNeedler. Compared to a plain muzzle, it adds electronics and a rechargeable battery, but it only works with the SixNeedler and requires tracer darts for the glow effect.
