Pronounced bur-nah, the Byrna HD (home defence) is a powerful non-lethal CO 2 hand-held self defense weapon that fires .68 caliber round projectiles. Inside each of the projectiles is a highly potent mixture of chemical irritants that include pepper spray, tear gas and PAVA (synthetic pepper spray). Byrna also offers .68 caliber solid hard plastic projectiles.
Firing these projectiles at an attacker from a distance of up to 18 metres, will deter and disorientate him, allowing you time to get away. This gives you the freedom to fire a Byrna without the consequences of a fatal outcome. Within 5min to an hour the attacker will be fully recovered.
