First Defense .2% Mk-9 Stream Oc Aerosol

The First Defense .2% Mk-9 Stream OC Aerosol is a professional-grade oleoresin capsicum (OC) dispersal system designed for law enforcement, correctional facilities, and security personnel managing crowds or de-escalating volatile situations. This Defense Technology product provides tactical-grade self-defense capability in a portable, non-lethal format that meets the operational requirements of trained users who need reliable, target-specific deployment.

The stream delivery mechanism distinguishes this product from foam or fog alternatives, offering precision application over a meaningful engagement distance. The First Defense Mk-9 employs a concentrated stream OC formulation at 0.2% concentration, engineered to project a strong, coherent stream rather than dispersing as mist or powder—critical for outdoor use, windy conditions, or scenarios where collateral exposure must be minimized. The trigger-handle design ensures positive control and rapid deployment, while the canister yields approximately 14 short bursts at an effective operational range of 18–20 feet.

Law enforcement, corrections, and security professionals benefit most from the First Defense Mk-9, especially in complex crowd management environments where discrimination between threat and non-threat is essential. Stream-based aerosol technology minimizes self-exposure risk and allows for precision targeting of a single subject without affecting bystanders, making it an ideal choice for those in high-stakes situations.
