AMMO Inc OPS (One Precise Shot) rounds were developed to meet a wide variety of demanding engagement scenarios typically experienced by law enforcement personnel in the line of duty. With a Hollow Point Frangible (HPF) projectile that transfers 100% of its energy into the target, these rounds track straight through a variety of soft barriers like drywall, plywood, car doors and auto glass. Upon entering soft tissue, the jacket and core separate with furious force of impact, resulting in mass force trauma.
