We get a two-for-one review from ASG Olsztyn as he goes over the Tracer NANO and LITE RGB trace units made by T328. The T238 NANO and LITE tracer units are designed for BB and Gel blasters. They attach to your blaster and illuminate special tracer BBs/Gel balls, letting you see the path of your shots in the dark. The LITE also offers an RGB version that creates a "rainbow of gunfire" effect without needing special ammo.
