The PRISim system is designed for both marksmanship and force option and force articulation training. A wide variety of lethal and less-lethal weapons are available for use with the simulator. For extra realism and for elevating the students’ stress level, instructors can use the integrated ShootBack system. The ShootBack cannon fires .68 caliber nylon balls at speeds up to 120-feet-per second. That’s enough velocity to sting a bit and remind a student to use cover in a gunfight.
