OWN THE NIGHT: Surge XL Day 'n' Nite edition is the next generation of blasters from the Gel Blaster team. Our newest addition is the most powerful blaster in our lineup! Comes with a velocity dial which adjusts blaster power from 170 to an astonishing 250 feet per second. Most Importantly, the Day 'n' Nite edition comes with our new Starfire Activator. The activator uses UV lighting technology to supercharge starfire gellets so they glow in the dark and produce a glowing tracer effect you have to see to believe.
