The Combined Tactical Systems 4510 frangible Impact+ munitions are spin-stabilized projectiles and deliver multi-effects of blunt trauma and dispersal of inert or marking powder on and around target. Although it is extremely accurate and consistent, accuracy is dependent on the launcher, using open sights vs. an improved sight, environmental conditions, and the operator. Effectiveness depends on many variables, such as distance, clothing, stature, and the point where the projectile impacts. This model comes with inert powder for training.
