Gorilla Rounds are high-carbon military grade steel .68 caliber projectiles weighing in at 17 grams. At 300 FPS these rounds deliver approximately 71 joules and 52 foot pounds of energy. The proprietary silicone embedded coatings reduce friction (drag) resulting in increased velocity, distance, and less lethal stopping power. With the ability to deliver bone crushing self-protection-shock and awe without fully lethal potential of traditional firearms. Most effective in close quarters up to twenty feet. These may be reused indefinite number of times and fired from any .68 caliber gas-powered marker or launcher. Click on the banner above for additional info.
