The First Strike .50 Caliber Ultra-Sphere Projectiles (USP) are a great addition to the First Strike projectile family. The First Strike USP balls are powder filled perfectly round projectiles that deliver what standard gelatin paintballs cannot; consistent, dimple free accuracy. The weather proof polystyrene shell ensures consistent performance in even the most inclement weather and can even endure the heavy spring pressure required in today’s magfed paintball guns.
Since these are filled with powder instead of paint, they are great for indoor training where clean up will be easier.
