Byrna's most powerful proprietary pepper and tear gas blend: OC, CS all in one shot, with quick-acting incapacitating effects, higher dispersion, and higher concentration of chemical irritants than any other round found on the market today. Byrna Max projectiles are designed for maximum stopping power. Physical symptoms of chemical irritants often result in disorientation and agitation, which can lead to a state of fear, anxiety and panic in would-be attackers. Upon impact the projectiles burst, creating a cloud of chemical irritant that rapidly disperses into the air to quickly incapacitate an attacker. Within seconds, the saturation area extends in all directions around the point of impact. Physical effects include: Burning in throat Wheezing, Gasping, Dry cough, Shortness of breath, Gagging, Inability to breathe, Nausea, Burning of the eyes, Burning of the lungs, Chest tightness, and Excessive salivation.
