The new OVERWATCH line by Liberty Ammunition was created at the request of special forces groups. These groups tested Civil Defense and were impressed with the way the projectile erupts upon entry into a target. The one issue they found was there not enough penetration. Liberty Ammunition answered! OVERWATCH projectiles are designed to function similar to the Civil Defense projectiles, but with deeper penetration due to the increase in weight. OVERWATCH ammunition is capable of penetrating 12”-16” in gel blocks. The OVERWATCH lineup is designed for Maximum Organ Displacement, (MOD). As always, OVERWATCH ammunition projectiles are made of solid copper alloy!
